A variable volume flow rotor pump comprising a pump housing (20) provided with a suction connection (44) and a pressure connection (46), an internally geared outer rotor (30) rotationally mounted inside the housing, and an externally geared inner rotor (28) which is eccentrically mounted therein and which can be driven by a drive shaft which is mounted parallel to the axis of the outer rotor (30) inside the pump housing. A rotatable adjusting ring (22), which is mounted coaxially in relation to the drive shaft, is also provided, the outer rotor being eccentrically and rotationally mounted therein. When seen in the direction of rotation, a slider (58) which can modify the size of at least one of the connections is provided between the pressure connection and the suction connection. |
