Definitions

  • the invention relates to a piston pump for delivery a fluid at low pressure and at higher pressure, being higher at low pressure in one pump cycle Delivery rate is given than at higher pressure, with one moved in a pump cylinder, under tension acted upon in its delivery end position of a pressure chamber Low pressure delivery piston, a high pressure delivery piston and an inlet and an outlet valve, further between the intake and exhaust valves a fluid delivery path is formed and the low pressure delivery piston against its bias into one The initial position of the conveyor must be moved back.
  • Piston pumps of this type are used, for example, by hand or motor-driven hand tools. This is about to a state of the art according to the US patents 5,575,627, 5,195,354 and 2,688,231. This prior art relates to motor-driven hand tools for crimping cable lugs or cable connectors. Furthermore, the subject of the invention but also meaning with regard to scissors, about cable shears. This is about the German Utility model 94 16 535 and the unpublished to refer to German patent application 196 49 932. In addition, such pumps also used in other areas of technology. It For example, U.S. Patents 2,845,033 and 674,381.
  • Two-stage pumps Numerous types of two-stage pumps are known. It is e.g. possible two different pump types to combine with each other and at the same time to drive, e.g. a gear pump for the low Pressure range and a piston pump for the high Print area. As soon as the required outlet pressure reaches the Working pressure of the low pressure pump exceeds their flow through a pressure relief valve in the tank returned.
  • Two-stage piston pumps are common, both for the low as well as for the high pressure sub-piston pumps be used.
  • One type is widespread the two pistons in the form of a pump tappet with two different diameters are united.
  • the hydraulic effective area is at the low pressure part the circular area between the two diameters and for the high pressure piston it is the entire cross sectional area of the small diameter.
  • Both Niederals even high pressure pumps each have one with the Tank connected inlet and one connected to pressure side Exhaust valve.
  • the US-PS 4,492,106 relates to a lever-operated hand tool in an embodiment for pressing Cable shoes.
  • a pump device which have a high pressure delivery piston and one Has low-pressure delivery piston.
  • the low pressure delivery piston consists of a spring-supported pipe section with a tube plate, which is the piston crown forms.
  • the low pressure delivery piston is replaced by a Continuation of the high pressure delivery piston against the spring force relocated, with hydraulic fluid from a reservoir is sucked in. Then moves the extension of the high pressure delivery piston back and the Low-pressure delivery piston delivers due to the pressure on it Spring the sucked hydraulic fluid in the work room.
  • the funding ends as soon as the Pressure in the delivery chamber no longer from the spring force is to be overcome. Then works at the well-known Pump only the high pressure piston.
  • the invention deals with the technical Problem, a piston pump to deliver a fluid to indicate at low pressure and at higher pressure, effective support with the simplest possible structure allows.
  • the fluid delivery path is also passed through the low-pressure delivery piston, with a valve blocking the movement of the low-pressure delivery piston in the delivery direction.
  • the valve in the low-pressure delivery piston is open, the pressure on both sides of the low-pressure delivery piston is practically the same.
  • the embodiment advantageously has a few individual parts.
  • valve in the low-pressure delivery piston In addition to the inlet and outlet valves, only the valve in the low-pressure delivery piston is required. The design is also simplified. There is only one pressure chamber for both the low pressure stage and the high pressure stage. Furthermore, it is provided that the movement of the low-pressure delivery piston takes place against its preload by the high-pressure delivery piston.
  • the high-pressure delivery piston can in particular act directly on the low-pressure delivery piston.
  • the high-pressure delivery piston preferably has a smaller cross-sectional area effective in terms of pumping than the low-pressure delivery piston.
  • the ratio can be, for example, 4: 1 with respect to the area of the low-pressure delivery piston to the area of the high-pressure delivery piston. Practically good values are also achieved with ratios of 6 to 7: 1.
  • the high-pressure delivery piston actuates the valve which is arranged in the low-pressure delivery piston and which blocks when the low-pressure delivery piston moves in the direction of delivery. Because the high-pressure delivery piston does not have to rest against the low-pressure delivery piston when the low-pressure delivery piston moves in the conveying direction, a valve which is very simple in construction, namely a plate valve, can be arranged in the low-pressure delivery piston in continuation of this idea.
  • the valve in the low-pressure delivery piston further preferably has a style-like extension or an actuating end passing through the piston head of the low-pressure delivery piston. Via this actuation end, the valve can be actuated in the manner described by the high-pressure delivery piston.
  • the preload of the low-pressure delivery piston in its delivery end position is advantageously achieved by a spring, more preferably by a helical spring (compression spring).
  • a spring more preferably by a helical spring (compression spring).
  • the spring acting on the low-pressure delivery piston biases the valve into the closed position.
  • the fluid volume in the piston pump, ie on the inlet side of the low-pressure delivery piston and in the pressure chamber is as small as possible.
  • the low-pressure delivery piston has a stylish extension on the back, for reducing the fluid volume between the inlet valve and the low-pressure delivery piston.
  • a projection on the rear wall can also be provided in the cylinder receiving the low-pressure delivery piston or a combination of these measures.
  • the pump cylinder has an operationally openable base. Due to the fact that the pump cylinder base can be opened operationally, it is possible, for example, to exchange or maintain the spring and / or the low-pressure delivery piston with the valve arranged therein in a simple manner.
  • the pump cylinder base can be screw-fastened in the pump housing in further detail.
  • the bottom of the pump cylinder is of a pot-like design with a screw-in thread on an outer edge of the pot. It is also possible, alternatively or alternatively, for the guide of the high-pressure delivery piston and possibly part of the adjoining piston crown to be screwed on and exchanged in this way.

  • the piston pump 1 can be used in a very wide variety of ways Find. With simple, manually operated pumps, the High pressure delivery piston operated by a hand lever and the ones already mentioned above motor-driven handheld devices just by a motor, like an electric motor. It is essential that first, without Load, an overdrive is desired, accordingly a high flow rate per stroke, and then under load higher pressures must be applied (at lower Delivery per stroke).
  • the piston pump 1 has a pump cylinder 2, in which against the bias exerted by a spring 3 a low-pressure delivery piston 4 is movable.
  • the Low-pressure delivery piston 4 also has a passage 5 for the hydraulic fluid, which is here is pumped.
  • the fluid passageway 5 is through a valve 6 designed as a check valve is closed. The valve 6 locks when the low pressure delivery piston 4 moves in the conveying direction and can open when the low-pressure delivery piston 4 opposes each other its direction of conveyance moves.

The valve 6 is closed and on the inflow side due to resulting Negative pressure via the opening inlet valve 9 Fluid is sucked from the reservoir into the inflow space. At the same time, fluid from the pressure chamber 7 via the open exhaust valve 10 displaced in the work space. It can be seen that the amount of fluid displaced here depends on the cross-sectional ratio of the Low-pressure delivery piston 4 to the high-pressure delivery piston 11. It becomes all the more fluid in the low pressure stage conveyed into the work space via the outlet valve 10, the greater the - effective - cross-sectional ratio of the two pistons.

  • the falling pressure or the compensation caused by the high-pressure delivery piston moving out 11 resulting volume increase leads to a wake of the low-pressure delivery piston 4. This is at the same time through the opening inlet valve 9 fluid from the reservoir sucked into the inflow 8.
  • the low pressure delivery piston 4 does not reach the end of delivery position 2a, but one for this in the conveying direction upstream position until an equalization of the volume share the moving out part of the high pressure delivery piston 11 is reached.
