Abstract
A rotary vane pump includes a pump housing, a stator, a rotor, a plurality of vanes which are accommodated in the rotor so as to be displaceable in the radial direction, so that they delimit a plurality of pump chambers between themselves, the stator and the rotor. A radially inner cam surface is provided, against which the vanes rest, wherein secondary chambers are delimited in the radial direction between the cam surface and the rotor and in the circumferential direction between the vanes, with a suction inlet and a pressure outlet being assigned to the secondary chambers.
