Vane cell pump has means for swirl-free orientated flow guiding of fluid and which comprise different spherical form of kidney shaped suction slots in control plate and end plate

摘要

The vane cell pump has an end plate (9) and a control plate (10) between which are located a rotor (3) and a cam ring (8). The end plate and control plate has means (16) for an at least approximate swirl-free orientated flow guiding of the fluid (2) and which comprise a different spherical form of kidney shaped suction slots in the control plate and end plate, or a different contour and/or spherical form of the kidney shaped pressure slots (14) in the control plate and end plate.
