Definitions

the invention relates to an oil supply device for an internal combustion engine, in particular for a crankcase of an internal combustion engine, according to the preamble of claim 1.
oil supply devices for an internal combustion engine, in particular in conjunction with a crankcase of an internal combustion engine, is already generally known from the automotive, industrial or ship engine industry.
This oil supply device is part of a lubrication system for the internal combustion engine, in which the oil is guided in the lubricating oil circuit.
an oil pump as a conveyor sucks the oil from an oil sump or an oil sump and conveys the sucked oil via an oil cooler and an oil filter to one or more crankcase-side main channels, from which the oil is then conveyed to the individual lubrication points.
engine components such as an oil filter unit
engine-mounted redundantly in a redundant design, thereby allowing an oil filter of an oil filter unit also during engine operation by appropriately switching from one oil filter unit to the other Decommissioning and changing the oil filter unit.
this is known in connection with switchable double filters in the field of marine engines.
such a double-filter switchable arrangement is known from US 5,178,237 US 2005/0022756 A1 in which the oil coming from the internal combustion engine is fed via a supply line to a first filter unit, from which the oil then flows back to the engine via a first return line.
a second filter unit arranged parallel to the first filter unit is switched off by corresponding valves during the operation of the first filter unit. If the second filter unit is now to be put into operation in order, for example, to service the first filter unit or replace the oil filter arranged there, then the valves of the first filter unit are closed and the valves of the second filter unit are opened accordingly.
this is an internal combustion engine, which is used in conjunction with oil production on oil fields and which is not operated here with conventional fuel but with oil.
an oil supply device for an internal combustion engine in particular for a crankcase of an internal combustion engine is provided, which has at least one oil reservoir and at least one conveyor, by means of which conveyor ⁇ I is guided from the oil reservoir via at least one flow channel to at least one main oil passage of a crankcase of the internal combustion engine wherein a plurality of oil filter units, for example a plurality of oil filter units each equipped with at least one oil filter, are provided in the flow path of the oil from the oil reservoir to the at least one main oil passage.
the oil supply means comprises a filter switching means, for example in the manner of a shuttle valve or the like, by means of which filter switching means the oil filter units are selectively switched into the flow path of the oil to the main oil passage that only a part of the oil filter units as at least one active oil filter unit from Oil is flowed through, while the other part of the oil filter units as at least one passive oil filter unit is not flowed through by the oil and can be serviced if necessary.
a switching unit preferably a single switching unit, which is passive in at least part of those switching positions of the filter switching device in which one part of the oil filter units is active and another part of the oil filter units is connected, a first pressure oil flow path from the oil reservoir to the at least one active oil filter unit releases and further produces a second exhaust or drainage flow path between the at least one passive oil filter unit and a discharge channel, wherein the discharge channel, a discharge device, in particular a suction device , assigned, by means of which the ⁇ I accumulated in the region of the at least one passive oil filter unit can be discharged, in particular sucked.
an oil filter replacement of the deactivated, passive oil filter unit can also be carried out while the internal combustion engine is running, without the residual oil accumulated in the passive, deactivated oil filter unit having to be drained off the engine for this purpose. Because of the assignment of a discharge device according to the invention, it is possible to simply discharge or suck off this oil accumulated in the switched-off, passive oil filter unit and feed it to the lubricating oil circuit of the internal combustion engine.
the discharge channel is assigned to the oil reservoir, for example an oil pan or the like, which forms part of a crankcase of the internal combustion engine, so that the oil, which has been drained off via the discharge channel and is sucked back into the oil reservoir, resumes the lubricating oil circuit of the internal combustion engine can be supplied by the oil supply device.
crankcase is to be understood here explicitly in a comprehensive sense and, for example, can be equated with the term "engine block”.
a suction device as a discharge device is therefore particularly necessary in order to be able to build up a sufficient pressure potential against unfavorable pressure conditions in the region of the crankcase during the engine or internal combustion engine operation for the discharge of the oil from the passive oil filter unit.
the suction device can basically be designed in different ways, for example by means of any suitable suction pump.
the discharge channel designed as a suction channel is assigned an ejector pump device as the suction device, by means of which the ⁇ I accumulated in the region of the at least one passive oil filter unit can be sucked off via the suction channel, wherein the ejector pump device can be acted upon by a partial pressure stream branched off from the pressure oil flow path to produce a suction pressure.
jet pump arrangement is thus ensured in a particularly simple and functionally integrated manner that a branched off from the pressure oil flow path partial flow from the anyway to be provided motor pressure oil supply in a dual function is simultaneously used as a driving medium for the Ejektorpump worn to, in corresponding switching position of the switching unit, in to suck the at least one passive oil filter unit accumulated residual oil as a suction medium.
the extraction by means of the ejector pump device can also be ensured in a simple and functionally reliable manner without great additional expenditure on components.
the ejector pump device can in principle be formed by a permanent ejector pump that is permanently actuated during internal combustion engine operation or, alternatively, can be configured by an ejector pump which can be actuated or switched on by an actuator at defined times.
the actuating device can in principle be designed and arranged so that a manual operation is possible.
an actuating device formed by a control device which can be correspondingly activated for actuating the ejector pump device at defined times. This will be discussed in more detail below in connection with a preferred specific embodiment of the switching unit.
the switching unit itself can basically be designed in different ways. Particularly preferred is a switching unit, the one Adjusting device which is adjustably received in a switch housing of the switching unit, leading to the oil filter units oil filter flow channels open into the switch housing and there in defined switching positions of the actuator either with the drain or suction or with the coming of the conveyor and also communicate in the switch housing opening pressure oil flow channel. It is understood that in principle even more switching positions are possible, as will be explained in more detail below.
the switching positions just described here relate essentially to those switching positions in which a preferred suction of residual oil from at least one passive, switched-off oil filter unit should be possible by means of the drainage or suction device.
Other switching positions are of course possible at any time.
the adjusting device itself can also be designed in different ways, for example by slide switch or the like. However, particularly preferred is the design of the adjusting device in the form of a shift drum, which is rotatably received and stored in a switch housing of the switching unit. By means of such a switching drum, the individual switching-roller-side control channels, as will be discussed in more detail below, can be brought into fluid communication with the correspondingly assigned pressure-oil flow channels or oil-filter flow channels by simple rotational movements.
the adjusting device in particular a switching drum, in a first switching position of the switching unit connects at least one first oil filter flow channel leading to at least one active oil filter unit by means of a control channel with a pressure oil flow channel, while at least one to at least one passive second oil filter unit guided second oil filter flow channel is flow-connected in this first switching position of the switching unit by means of a control channel with the discharge or suction channel.
the adjusting device in particular a shift drum, moved to a second switching position, in which now at least one active second oil filter unit and passive at least a first oil filter unit, the at least one second active to the second oil filter unit Oil filter flow channel is flow-connected by means of a control channel with a pressure oil flow channel, while the at least one guided to the at least one passive first oil filter unit first oil filter flow channel by means of a control channel to the drain and suction channel is flow-connected.
control channels of an adjusting device in particular a shift drum, a different flow control is possible in a simple manner only by switching or displacing the adjusting device without the need for this component-consuming valves or the like.
the configuration of the adjusting device as a shift drum is particularly preferred.
a control device having a plurality of control channels and being designed as a shift drum, it can have two control channels which are arranged in the first switching position such that a first control channel connects the pressure oil flow channel to the first oil filter flow channel a second control passage connects the second oil filter flow passage to the drain passage.
these control channels are then preferably arranged so that the first control channel connects the first oil filter flow channel with the discharge channel, while the second control channel connects the second oil filter flow channel with the pressure oil flow channel.
the suction device formed by Ejektorpump pain is preferably arranged in the switch housing and is switch housing side with the at least partially constituent of the switching housing forming suction in flow communication, in particular such that a nozzle of the Ejektorpump Vintage protrudes into the suction.
a branch channel diverges from a flow channel forming the pressure oil flow path, in particular from a flow channel or flow channel section of the pressure oil flow path led to the switching unit, into the ejector pump device, preferably in the region of one Nozzle of Ejektorpump issued, opens.
the pressure oil supply for the ejector pump means can be ensured in a functionally reliable manner.
the branch channel extends at least partially in the switch housing, whereby the function integration in connection with the switching unit can be further increased and this switching unit can be installed as easy to be manufactured module component.
the branch channel can also be designed separately and independently of the switch housing, for example by means of a hose and / or pipe branching off from a pressure oil flow channel.
a switchable shut-off device in particular a shut-off valve or the like is arranged as a shut-off, which is switchable between a position releasing or occluding the flow connection to the ejector.
the circuit of the shut-off device can basically also be done manually. However, particularly preferred is the circuit by means of a control device as a function of defined shut-off parameters.
shut-off device is so coupled to the adjusting device, in particular with a shift drum, the switching unit, that it can be brought in defined switching positions of the adjusting device or the shift drum in their flow connection to Ejektorpump adopted releasing or closing position , That is, with such a structure, the actuator is then displaced to the desired position in response to an operation of the switch unit.
the adjusting device formed in particular by a shift drum can also be designed and / or adjustable so that this adjusting device can be adjusted in internal combustion engine operation in a position in which a part of the oil filter units active and another part of the Oil filter units is switched passively and in which further the suction device, in particular also in an optionally produced flow connection between the at least one oil filter unit and the suction channel, is not activated.
the adjusting device and thus the switching unit can of course also be designed so that the adjusting device can be displaced into such positions, in which - despite active circuit of a part of the oil filter units and despite passive switching of another part of the oil filter units - not necessarily an extraction is made or provided.
the suction of a passively connected oil filter unit enabling switching positions of course, other switch positions with active and / or passive connected oil filter units are possible.
the actuation of the suction device which is in particular formed by an ejector pump device, can of course also take place in a different manner, that is to say independently of the switching position of the switching unit, for example by magnetic and / or electrical switching devices , which can be operated separately and independently of an actuation of the switching unit.
the adjusting device in particular a switching drum, in particular with regard to their control channels, can be designed and / or arranged such that the adjusting device at standstill of the internal combustion engine and thus also at switched-off conveyor is adjustable in a flow connection between the suction channel and an associated oil filter unit producing position, so that in the respective oil filter unit accumulated oil can flow out of this due to gravity on the drain or suction, in particular can flow through the suction into an oil reservoir of the crankcase ,
the oil filter units should preferably be arranged in the mounted state geodetically above the switching unit.
the adjusting device in particular a switching drum, in particular with regard to their control channels, also designed and / or adjustable so that all oil filter units are actively switched and can be flowed through by the oil.
an embodiment is particularly preferred, in which at least one main oil filter unit is provided, which is connected to other components of the oil supply device or the lubricating oil circuit, such as an oil cooler and / or a blow-by separator and / or an oil pump as a conveyor and / or optionally other integrated in the lubricating oil circuit components, is integrated into a separately installable oil module, while on the other hand, the at least one, a redundancy forming oil filter unit is designed as a separately mountable additional filter unit.
the invention further relates to a suitable process control for operating an oil supply device for an internal combustion engine, in particular for a crankcase of an internal combustion engine, with one or more features of the oil supply device according to the invention, as they has been described in detail above.
the applicant expressly reserves the formulation of further method claims for operating such an oil supply device.
a crankcase 1 of an internal combustion engine which for example has a cylinder block 2 in V-arrangement, in which in the usual way, which is not shown here, cylinder pistons and valves are guided and stored.
the one in the picture plane the Fig. 1a Lower region of the crankcase 1 here has an oil reservoir 3 forming an oil reservoir, is received in the oil 4, which is supplied by means of an oil supply device 5 according to the invention a lubricating oil circuit not shown here in detail.
an oil pump 6 oil from the oil pan 3 as a pressure oil via a pressure oil flow channel 8 to a switching unit 7, which will be described in more detail below, promoted or pumped.
the pressure oil flows through a first control channel 9, which is fluidly connected to an oil filter flow channel 10 leading away from the switching unit 7.
This oil filter flow channel 10 branches into a first channel section 10a and a second channel section 10b, which are respectively led to an oil filter unit 11, in which the pressure oil flows through an oil filter 12 shown here only extremely schematically, before it via another pressure oil flow channel thirteenth to a here formed, for example, as a shuttle valve 14 filter switching device flows, here the flow of the pressure oil from the pressure oil flow channel 13 via one of the Shuttle valve 14 away leading channel section 15 to a main oil passage 16 releases.
the oil supply device also comprises two second oil filter units 17, which have an oil filter flow channel 18 and channel sections 18a, 18b branched off from it and lead to one of the second oil filter units 17 with a second control channel 19 the switching unit 7 are in flow communication.
This second control channel 19 is further in fluid communication with a suction channel 20, which is assigned to the oil pan 3 and opens into this.
the suction channel 20 is associated with an ejector 21, which, as in particular from Fig. 1b It can be seen that an enlarged view of the switching unit 7 of Fig. 1a shows, with a nozzle 22 in the outgoing from the second control channel 19 suction channel 20 opens.
the switching unit 7 comprises a here in partial section drawn switch housing 23 in which a control channels 9, 19 having and subsequently described in more detail shift drum 24 is rotatably received.
the ejector 21 is mounted in this switching housing 23 in the region of the suction channel 20 in a pump recess 25 so that the nozzle 22 of the ejector 21 projects in the manner described above in the switch housing side region of the suction channel 20.
suction is thus to be understood in a comprehensive sense and includes both the switch housing-side channel portion and the outside of the switching housing 23 extending channel portion, as he, for example, from Fig. 1a is apparent.
flow channel is also to be understood here in a comprehensive sense and encompasses both free conduits formed, for example, by pipes or hoses, and channels integrated in components or the like.
Fig. 1b branches off upstream of the switching unit 7, a branch channel 26 from the pressure oil flow channel 8 and is here, either integrally in the switch housing 23 of the switching unit 7 or by means of a separate line outside the switching housing 23 of the switching unit 7 to the ejector 21st guided, so that pressure oil is withdrawn from the pressure oil flow channel 8 in the form of a partial flow in a manner to be described and the ejector 21 can be supplied as a driving medium.
This branched off from the pressure oil flow channel 8 partial flow of the pressure oil is then through the nozzle 22, which may for example have a nozzle size between 1 to 5 mm (depending on the engine size, the flow rates, etc.), in the downstream of the nozzle 22 subsequent mixing chamber section 27 of the suction channel 20 is injected, where it exerts a suction effect in the second oil filter units 17 flow-connected to the oil filter flow channel 18 and the channel portions 18 a and 18 b via the second control channel 19. This can then in the in the Fig.
the second oil filter units 17 are here part of a so-called oil module 31, which also includes an oil cooler 32 shown here only schematically and in addition to the oil filter unit 17 and optionally other components of the lubricating oil circuit forming components or components.
oil modules 31 are then mounted motor-fixed in a conventional manner.
two oil pump 6 are provided as conveyors, which are each associated with a guided to the switching unit 7 pressure oil flow channel 8a and 8b.
each oil module 31 is assigned a shuttle valve 14, which is the flow path from Pressure oil flow channel 13 to the two main oil channels (16) unlocks here.
the ejector 21 also opens again into this suction channel 20 and is acted upon via the here branched off from the pressure oil flow channel 8a branch channel 26 with a partial flow of the pressurized oil, whereby a suction effect on the collected in the second oil filter units 17 residual amounts of oil 28 is applied and this be sucked against the prevailing pressure conditions in the crankcase 1 via the flow channels 18a, 18b and the suction passage 20 and finally introduced into the oil pan 3.
Fig. 1d is the one in the Fig. 1c shown switching unit 7 in an enlarged embodiment, so that individual details are even better visible.
the change-over valve 14 forming a filter unit switching device is switched over, the two second oil filter units 17 are actively switched (FIG. Fig. 2a ).
the two oil filter units 17 flowing through pressure oil are conveyed through the channel section 15 in the main oil passage 16.
the switching roller 24 of the switching unit 7 in the switch housing 23 is preferably rotated simultaneously with the switching of the shuttle valve 14 so that now the second control channel 19, a flow connection between the pressure oil flow channel.
the rotation of the shift drum 24 brings the first control channel 9 into flow communication with, on the one hand, the suction channel 20 and, on the other hand, the oil filter flow channel 10, which opens into the first oil filter unit 11 with its two channel sections 10a, 10b.
a suction effect on a residual oil amount 34 in the two passively connected first oil filter units 11 are applied, whereby this amount of residual oil 34 is conveyed through the channel assembly 10, 10a, 10b, the first control channel 9 and the suction channel 20 in the oil pan 3 ,
the ejector 21 operates against the prevailing pressure conditions in the crankcase, that is to say that the ejector 21 builds up a pressure potential against unfavorable pressure conditions in the crankcase chamber in order to allow the residual oil quantity 34 to be extracted from the two first oil filter units 11.
shut-off valve 35 in the region of the branch channel 26, an obturator formed here by way of example by a shut-off valve 35 is provided, by means of which the diversion of pressure oil from the pressure oil flow channel 8 to the ejector 21, depending on Switching position of the shut-off valve 35, can be released or locked.
the suction of the residual oil quantity depending on the switching position of the shift drum 24, can be effected from the respectively passively connected oil filter units via the ejector 21.
shut off shut-off valve 35 takes place during operation of the engine against it regularly no outflow of residual oil from the passively connected oil filter units instead, since there is no sufficient suction or suction acts on the residual oil quantities in the passively connected oil filter units.
shut-off valve 35 To actuate the shut-off valve 35 can be provided that this is manually operated, for example, during ongoing maintenance. Alternatively, however, it may also be provided that the shut-off valve 35 is switched in accordance with control via a control device of the oil supply device 5 in the open position. According to a particularly preferred embodiment, it is provided that the shut-off valve 35 is switched to its open position when the shift drum 24 at a certain shift drum position, as shown in the Fig. 1b and 2 B is shown, at the same time, the shut-off valve 35 is operated to adjust this depending on the switching position of the shift drum 24 between an open and a closed position.
a shut-off valve 35 in the in the Fig. 3 shown manner can be arranged.
the switching of the shift drum 24 and thus the switching unit 7 can be carried out separately and independently of an adjustment or circuit of the shuttle valve 14. But here, too, is basically a coupling of the circuit of shuttle valve 14 and switching unit 7 possible.
a switching unit 7, which is part of the oil supply device 5 according to the embodiment of Fig. 1c is.
the control channels 9a and 9b respectively displaced by rotation of the shift drum or replaced by such control channels of the shift drum 24, which now produce a flow connection of the pressure oil flow channel 8a with the oil filter flow channel 18a.
the here the passively connected side associated oil filter flow channels 10 a and 10 b are now flow-connected via a control channel 19 to the suction channel 20.
the switching unit 7 in particular with regard to their control channels, of course, also be designed so that in defined switching positions one of the pressure oil side associated control channel active is associated with switched oil filter unit, while the passively connected oil filter unit switching roller side seen no control channel is assigned and, accordingly, no flow connection between them and the suction channel is made.
One Such a structure of a shift drum or such a structure of an arrangement is not shown here, but in principle possible and represents a switching to the above-described positions further switching possibility or possibility of designing the shift drum and thus the switching unit.
the shift drum 24 may be formed in conjunction with their control channels so that, for example, in a faulty switching all oil filter units are actively connected and are flowed. This case is not explicitly shown here.
the switch housing 23 itself may be formed in several parts, which is shown there only by way of example by means of a plate 36 and a lid 37.
the openings of the shift drum 24 are shown here only schematically without running inside the control channels, the different opening sizes to symbolize the various design and circuit variants of the control channels or the shift drum 24.
the Fig. 3 shown here by way of example hand-operated shut-off valve 35, which can be brought by twisting in the desired position.
This switching unit 7 can then be installed in a modular manner.
