- Figure 4 shows a detail of Figure 3 in longitudinal section.
- a vane pump 1 is shown with a pump housing 2 in different views.
- the pump housing 2 comprises a suction port 3, via which a hydraulic medium, preferably oil, is sucked.
- a displacer 4 and a pressure plate 5 is mounted in the pump housing 2.
- the displacer 4 of the vane pump 1 comprises a contour ring or cam ring, within which a rotor is rotatably driven with wings.
- the drive of the displacer 4 is preferably carried out by the side facing away from the suction port 3 of the displacer 4, so in Figure 2 from the left.
- the wings are preferably guided displaceably in the radial direction in the rotor.
- the contour ring or lifting ring has a stroke contour, which is designed so that at least one, preferably two substantially crescent-shaped delivery chambers are formed. These are passed through by the wings, wherein two pump sections are realized, each with a suction and a pressure range.
- the displacer 4 is located on a displacement side 11 of the pressure plate 5 at.
- Suction port side 12 of the pressure plate 5 faces the suction port 3.
- the suction port 3 is connected via a suction channel 14 with suction pockets 15, 16 in connection, which are arranged in the form of depressions, unlike shown in Figure 1, on the displacement side 1 1 in the vicinity of the suction regions of the displacer 4.
- the suction pockets 15, 16 do not extend through the pressure plate 5.
- the suction pockets 15 and 16 are open radially on the outside and open into a suction connection space 17 which connects the two suction pockets with each other and with the suction channel 14.
- the pressure plate 5 there are further provided two kidney-shaped pressure passage holes 18, 19 extending through the pressure plate 5.
- the pressure passage holes 18, 19 connect the pressure areas of the displacer 4 with a pressure chamber on the suction connection side 12 of the pressure plate 5.
- the pressure chamber is connected via a pressure connection to a consumer in connection with which the suctioned via the suction port 3 hydraulic medium, in particular the oil, with the help the vane pump 1 is promoted.
- the pressure plate 5 has, as seen in Figure 1, the shape of a circular disc 20 with two suction pockets 15, 16 on the displacement side 1 1 and the two kidney-shaped pressure passage holes 18, 19.
- the suction channel 14 extends from the displacement group 4 radially outside the pressure plate 5 through the pump housing 2. By passing past the pressure plate 5 suction duct 14 increases the space requirement of the vane pump 1 in the radial direction.
- FIGS. 3 and 4 a similar vane pump 41 as in FIGS. 1 and 2 with a pump housing 42 is shown in different views.
- the radial space requirement of the pump housing 42 is reduced by the fact that a pressure plate 45 is installed, the shape of which deviates from the usual circular shape.
- the pressure plate 45 has a displacer side 51 and a suction port side 52 and performs the same function as the pressure plate 5 in the vane pump 1 shown in FIGS. 1 and 2.
- a suction channel 54 runs, as can be seen in FIG. 3, in the axial direction radially between the pressure plate 45 and the pump housing 42.

- Suction channel guide of the pump housing 42 can be avoided.
- the pump housing 42 can be realized more easily than a cost-effective die-cast solution.
- Another advantage is a more even deflection of the pressure plate 45 in the operation of the vane pump 41.
