Definitions

  • the invention relates to an oil pan-filter combination, in particular of an engine oil circuit of an internal combustion engine, in particular of a motor vehicle, with an oil pan, an oil filter arranged on or in the oil pan, which comprises an openable filter housing with a housing interior in which a filter element can be arranged interchangeably, the Housing interior of the filter housing is connected by means of at least one housing passage to a pan interior of the oil pan, which can be closed by means of a housing passage closure device.
  • an oil filter device for internal combustion engines is known with an oil filter housing which is integrally connected to an oil pan and arranged in a suspended manner with a geodetically lower opening for installing and removing a filter insert.
  • the opening of the oil filter housing is assigned a cup-shaped closure cover which can be introduced into the oil filter housing for opening and closing.
  • the closure cover in the closed position by means of a free pot section and a ring seal opposite a drain opening arranged downstream in the oil filter housing into the oil pan forms a drainage barrier.
  • the drainage block can be removed by opening the cover with a twisting motion.
  • an assembly which has a first and a second housing structure.
  • An oil filter for example, is accommodated in the first housing structure, and at least one channel structure is accommodated in the second housing structure, which is suitable for conveying the fluids in the oil circuit.
  • the EP 2 236 779 B1 Figure 12 shows an oil pan including a container defining a drain port for selectively draining fluid from the oil pan, a wall defining a filter cavity in fluid communication with a receiving passage and a discharge passage of the oil pan, the receiving passage being in fluid communication with the container the filter cavity and the dispensing passage enables fluid communication from the filter cavity to the container.
  • the invention is based on the object of designing an oil pan / filter combination of the type mentioned at the outset, in which a closure element can both open the housing passage and allow the oil to be drained from the oil pan / filter combination.
  • the oil sump has an oil drain opening which can be closed with a closure element, the at least one housing passage having a sealing section on its side facing the oil drain opening and the closure element having a closure section matching the sealing section on an area facing the housing passage which can cooperate to close the housing passage with the sealing portion closing.
  • the closure element has two sealing points or closure points, at each of which the housing passage and the oil drainage opening can be closed.
  • the closure element When the closure element is removed, the housing passage and the oil drainage opening are released. In this way, both the housing passage and the oil drain opening can be controlled with just one closure element. This reduces the assembly effort and the component effort.
  • the oil can be drained from a storage volume, in particular the oil pan, and a second volume, in particular the filter housing, by removing the closure element. Different fluids can be held in the two volumes.
  • the oil pan can contain contaminated oil, so-called crude oil, which flows back past the lubrication points to the geodetically deepest point and collects in the oil pan.
  • the pressure in the oil pan can be approximately the same as in a crankcase of the internal combustion engine.
  • the second volume can be formed by the filter housing at least with. Depending on the direction of flow of the oil through the filter element, it can be filled with purified oil, so-called pure oil, which has previously flowed through a filter medium of the filter element, or it can be filled with crude oil that is in the filter housing before the oil flows through the filter medium be.
  • the pressure in the filter housing can be higher than in the oil pan.
  • the pressure in the filter housing can be similar or the same as the pressure in the oil pan.
  • the internal pressure of the filter housing and oil pan can be equal to the ambient pressure outside the internal combustion engine.
  • the oil pan-filter combination is in the so-called "pressureless" state.
  • the closure element In the operational state of the oil pan / filter combination, the closure element is in its closed state.
  • the housing passage is closed with the closure section of the closure element.
  • the interior of the filter housing is fluidly separated from the interior of the oil pan.
  • An oil drain sealing section of the closure element closes the oil drain opening and seals the tub interior from the environment.
  • a largest diameter of the housing passage can advantageously be smaller, at least in the sealing section, than a smallest diameter of the oil drain opening.
  • a largest diameter of the closure section of the closure element can also be smaller than a smallest diameter of an oil drain closure section of the closure element that matches the oil drain opening. In this way, the closure element can easily be introduced through the oil drainage opening.
  • the sealing section and the oil drain opening are coaxial with a common axis.
  • the closure element can thus be introduced in a straight line in the direction of the axis from the outside through the oil drain opening to the housing passage, in particular the sealing section.
  • the closure element can advantageously be introduced and removed in a simple manner by means of a rotary and / or plugging movement with respect to the common axis.
  • an axial extension of a housing sealing area with respect to the common axis, in which the closing section rests tightly against the sealing section of the housing passage in the closed state of the closing element is smaller than an axial extension of an oil drain sealing area in which, in the closed state, an oil drain closing section of the closing element is close to an oil drain sealing section of the oil drain opening is applied.
  • the closure element can clear the oil drain opening.
  • the closure element can be completely removed from the discharge opening.
  • the oil contained in the tub interior can drain through the oil drainage opening. Any oil still contained in the housing interior can flow through the housing opening into the tub interior.
  • the housing passage and the oil drainage opening can be opened up in stages by continuously or step-by-step removal of the closure element.
  • the common axis in the usual installation position of the oil pan / filter combination, can run obliquely downward when viewed from the housing passage in the direction of the oil drain opening.
  • the sealing section of the housing passage can be arranged spatially above the oil drain opening.
  • a gradient of the housing passage between the housing interior of the filter housing and the pan interior of the oil pan can thus be implemented.
  • the oil contained in the interior of the housing can thus flow more easily and better into the interior of the tub.
  • the oil drain opening can overall be arranged spatially deeper in the oil pan.
  • the closure element can be inserted into the oil drain opening at an angle from below.
  • the common axis can also run horizontally or vertically.
  • the filter housing can have an insertion opening for the filter element, which can be closed with a housing cover, and the housing cover can have at least one securing recess, and the closing element can have a securing section, which in the correct installation position of the housing cover in the closed state of the Closure element can engage in the at least one securing recess.
  • the housing cover can be secured in the correct installation position with the closure element. It can thus be prevented that the housing cover can be separated from the filter housing without the closure element having been at least partially removed.
  • an axial extension of the safety section in the direction of the common axis can be greater than an axial extension of the housing sealing area. In this way, when the closure element is removed, the housing passage can be released before the securing of the housing cover is released.
  • the housing cover can advantageously be arranged and removed in or on the insertion opening by means of a rotary and / or plugging movement.
  • the securing recess can advantageously be arranged coaxially to the common axis of the sealing section of the housing passage and the oil drain opening.
  • the securing section can advantageously be arranged at the free end of the closure element.
  • the housing cover can advantageously have at least one fluid channel which connects the housing interior to the housing passage or which forms the housing passage.
  • the fluid channel can be at least one passage opening running from radially inside to radially outside with respect to a rotation and / or plug-in axis of the housing cover.
  • the at least one passage opening can advantageously open into an annular space.
  • the annular space can extend circumferentially with respect to the axis of rotation and / or plug-in axis of the housing cover on the radially outer circumferential side of the housing cover. When the housing cover is in the correct installation position, the annular space can be connected to the at least one housing passage or a section of the housing passage in the housing base body.
  • the closure element can have an external thread which can be screwed to a corresponding internal thread in the area of the oil drainage opening.
  • the closure element can be screwed stably and precisely into the oil drain opening by means of a screw connection.
  • the sealing section can be released precisely and continuously when the closure element of the housing passage is unscrewed.
  • a load on a seal arranged approximately between the sealing section and the closure section, in particular an O-ring seal, when closing and opening the closure element can be reduced by the screwing movement.
  • an approximately step-wise opening of the housing passage and the oil drain opening can be simplified and improved in this way.
  • a seal in particular an O-ring seal, can be arranged between the closing section of the closing element and the sealing section of the housing passage.
  • the sealing of the closed housing passage can be improved by means of the seal. In this way, even with possible pressure differences between the volumes connected to the housing passage, a fluid flow, in particular an oil flow, through the closed housing passage can be prevented.
  • the seal can advantageously be arranged on the closure element. In this way, it can be introduced into the oil drain opening together with the closure element.
  • the closure element can advantageously have a corresponding sealing groove for receiving the seal.
  • a cross section of the closure section can taper towards the free end of the closure element, in particular the closure section can taper conically. It can thus be achieved that when the closure element is removed, an opening gap between the closure section and the sealing section of the housing passage can be enlarged more evenly.
  • a cross section of the sealing section can correspondingly taper towards the housing interior.
  • the contours of the closure section and of the sealing section can advantageously be adapted to one another. To this In the closed position of the closure element, the closure section can lie flat against the sealing section. A sealing function can thus be improved.
  • the contours of the closure section and the sealing section can be optimized in such a way that a separate seal can be dispensed with.
  • the filter housing can be arranged outside the oil pan. In this way, the filter housing can be easily accessible from the outside. Furthermore, a separation, in particular a seal, of the pressure space in the housing interior from the pressureless space in the tub interior can be simplified.
  • the filter housing can advantageously be connected in one piece to an oil pan housing of the oil pan. In this way, the oil pan and the filter housing, in particular the housing base body, can easily be produced together.

  • Oil is received in a pan interior 25 of the oil pan 12 and runs back into the oil pan 12 from the lubrication points and cooling points of the internal combustion engine.
  • An oil sump 26 extends as far as an oil level 28.
  • the pressure from the crankcase of the internal combustion engine prevails in the oil pan 12, which pressure almost corresponds to the ambient pressure in the case of an internal combustion engine that is shut down for an oil change, for example.
  • the tub interior 25 can therefore be referred to as a "pressureless space".
  • the operational state shown of the oil pan-filter combination 10 is closed with an oil drain screw 32.

  • a sealing effect is improved, so that even if there is a pressure difference between the interior of the housing 50 and the tub interior 25, as can usually be the case when the internal combustion engine is operating, no oil can pass through the housing passage 48.
  • the axial extension 58 of the housing sealing area 56 is smaller than the axial extension 44 of the oil drain sealing area 42. In this way, when the oil drain screw 32 is unscrewed, the housing passage 48 is first opened, the oil drain opening 30 remaining closed. In this way, pressure equalization can take place between the housing interior 58 and the tub interior 25. Oil can flow through the housing passage 48. Only after the oil drain screw 32 has been completely unscrewed is the oil drain opening 30 released so that the oil can flow out of the tub interior 25.
