Definitions
- the invention relates to a vane pump for conveying a pressure medium from a container to a consumer.
- the rotor has radially directed slots in which blades are slidably inserted.
- Working chambers are formed between the cam ring, the rotor and the vanes, which are delimited in the axial direction by control surfaces of adjacent control plates.
- the rotor set is inserted into a pressure-filled interior of a housing, which consists of a bearing housing and a housing cover.
- the rotor is mounted in the bearing housing by means of a drive shaft which is supported on the housing cover in an axial direction.
- a suction connection for connecting the container and a pressure connection for connecting the consumer are arranged in the bearing housing.
- a flow control valve is arranged in the bearing housing for the control of the pressure medium delivered to the pressure connection.
- a pressure relief valve is arranged in the bearing housing. Suction and pressure channels that connect the working chambers with the suction connection, the flow control valve and the pressure relief valve are also arranged in the bearing housing.
- Such a vane pump is known for example from US-A-5 098 259.
- This pump has a very compact design.
- a cylindrical fit between the housing cover and the bearing housing results in an expansion of the housing cover in this area.
- the fitting must be carried out very precisely since the drive shaft has a second bearing in a control plate in addition to its bearing point in the bearing housing, and this in turn in the Housing cover is centered.
- the production of the different fitting parts results in considerable manufacturing costs. Further costs arise when assembling the bearing housing and the housing cover in that a seal between the two parts must be fitted very carefully so that it is not sheared off when the housing cover is pushed over the bearing housing.
- the invention has for its object to improve the known pump so that the manufacturing and assembly costs can be reduced.
- the seal between the housing cover and the bearing housing can be done with a simple flat gasket. However, it is expediently designed as an 0-ring in an annular groove in one of the two flat surfaces of the housing cover or bearing housing.
- FIG. 1 shows a longitudinal section through the vane pump according to the invention
- FIG. 2 shows a plan view of the vane pump according to arrow II in FIG. 1, with partial cutouts.
- the vane pump serves to convey a pressure medium from a container, not shown, to a consumer, not shown, which is formed, for example, by an auxiliary power steering system.
- a rotor set 3 is inserted in a pressure medium-filled interior 1 of a housing 2.
- the rotor set 3 consists of a cam ring 4 and a rotor 5.
- the rotor 5 is arranged in the interior of the cam ring 4 and has radially directed slots in which blades 6 are slidably inserted. Between the curve ring 4, the rotor 5 and the vanes 6, working chambers are formed which are delimited in the axial direction by control surfaces of adjacent control plates 7 and 8.
- the housing 2 is composed of a bearing housing 10 and a cup-shaped housing cover 11.
- the rotor 5 is mounted in the bearing housing 10 via a drive shaft 12.
- the bearing point in the bearing housing 10 is the only bearing of the drive shaft 12. This means that the drive shaft 12 is not supported in the housing cover 11 in the radial direction. Rather, the drive shaft 12 is supported on the housing cover 11 only in the axial direction.
- the bearing housing 10 In the bearing housing 10 there is a suction connection 13 for the connection of the container and a pressure connection 14 for the connection of the consumer.
- a flow control valve 15 is also arranged in the bearing housing 10 for the control of the pressure medium delivered to the pressure connection 14.
- a pressure relief valve 16 is also contained in the bearing housing 10.
- the design of the flow control valve 15 and the pressure relief valve 16 is generally known, for example from US Pat. No. 5,098,259, and is therefore not described in more detail.
- suction and pressure channels which connect the working chambers to the suction connection 13, the flow control valve 15 and the pressure relief valve 16 are arranged in the bearing housing 10. These channels are also generally known and are therefore not described in detail.
- the pressure limiting valve 16 can be integrated in the flow control valve 15. In the preferred embodiment, however, the two valves are arranged separately from one another.
- the bearing housing 10 has a flat surface 17 on its side facing the housing cover 11.
- the housing cover 11 has a flat surface 18 on its side facing the bearing housing 10.
- a seal preferably in the form of an O-ring 20, which is inserted in an annular groove open in the axial direction in the bearing housing 10 or in the housing cover 11.
- the two housing parts, bearing housing 10 and housing cover 11, have very simple shapes and can therefore be pre-cast or prefabricated essentially using the die-casting method.
- the housing cover 11 is fastened to the bearing housing 10 by screws 21 and is centered on the bearing housing 10 only by the screws 21. A further centering of the two parts with respect to one another is not necessary since no other parts are adjusted or centered in the housing cover 11.
- the drive shaft 12 is only supported in the radial direction in the bearing housing 10 and is supported only in the axial direction on the housing cover 11. In the pulling direction, the drive shaft 12 is held axially via a locking ring 22, the rotor 5 and the control plate 7.
- sealing ring 23 Between the housing cover 11 and the control plate 8 there is only one sealing ring 23, which on the one hand separates the interior space 1 which is subjected to high pressure from the drive shaft 12 and on the other hand provides an elastic link between the housing cover 11 and the control plate 8 for gap compensation.
- the sealing ring 23 has the task of pressing the control plate 8, the cam ring 4 and the control plate 7 onto the surface 18 when the pump is at a standstill in order to Compensate manufacturing tolerances.
- the screws 21 are located outside the interior 1, so that no additional sealing is required in this area.
- cam ring 4 and the control plates 7 and 8 are centered on the bearing housing 10 by two pins which are known per se and are therefore not described in more detail. Further centering is not necessary.
- the structure of the vane pump according to the invention enables very simple assembly: the various parts only have to be stacked on top of one another and then screwed together.
- the O-ring 20 cannot be sheared off during assembly.
