Abstract (en)
[origin: WO9846884A1] A vane-cell pump has a rotor that receives a plurality of radially movable vanes, a lifting ring which surrounds the rotor and forms at least one suction and one pressure region, and at least one compression plate which forms a lateral delimiting surface of the suction and pressure regions. When the vane-cell pump is in operation, a pressure is applied to the side of the compression plate opposite to the suction and pressure regions. The vane-cell pump is characterised in that the surface (17; 19) of the compression plate (13; 15) which faces the rotor (5) has a concave shape in the unpressurised state of the vane-cell pump (1).
