VANE PUMP

摘要

The invention relates to a vane pump comprising a pot-shaped housing, a rotor which is rotatably mounted in the housing, a plurality of vanes mounted in the rotor so as to be orthogonally displaceable in relation to the rotational axis, the distal tips of the vanes lying on an internal circumferential surface, which delimits a first working chamber, and thus dividing the first working chamber into a suction chamber and a pressure chamber. The vane pump further comprises a suction connection for the suction chamber and a pressure connection for the pressure chamber. The length of the suction chamber in a circumferential direction is smaller than the length of the pressure chamber in a circumferential direction.
