Sliding vane pump has rotor with radially aligned slits in its circumference with distance between slit flanks increasing radially outwards

摘要

The pump has a rotor (1) mounted rotatable inside a lift ring (8) which forms a suction area and compression area. The rotor has radially aligned slits (5) in the circumferential area and the distance between the two slit flanks of a slit increases radially outwards. The flanks of one slit are arranged parallel to each other in a radially inner first area and at a distance increasing outwards from each other in a radially outer area.
