Abstract (en)
A vane pump assembly has a rotor pump (2) with a pump housing (10), and a pump zone (12). A rotor (16) rotates within the pump zone, with sliding vanes (18) against the inner peripheral wall (34) to divide the pump zone into two chambers. The vane pump assembly has a rotor pump (2) with a pump housing (10), and a pump zone (12). A rotor (16) rotates within the pump zone, with sliding vanes (18) against the inner peripheral wall (34) to divide the pump zone into two chambers. The vanes have a relative movement in relation to the rotor and the inner wall, and at least one of the moving components has an insert (20,22) forming a mounting, of metal, ceramics, a sintered material or a plastics. The rotor and/or the vane and or the inner wall of the pump zone are of a plastics material.
