Abstract

The invention relates to a volumetric flow variable rotor pump (1) having a pump housing (2) having a suction connection (3) and a pressure connection (4), an outer rotor (9) accommodated in an actuator (7) and having an eccentric outer rotor (9). arranged, drivable inner rotor (10) with external teeth (10a), wherein the number of teeth of the external teeth is greater than that of the internal teeth by one, the internal and external teeth are engaged and the volume flow by a change in position of the actuator (7) is variable , DOLLAR A It is proposed that the outer toothing (10a) is superimposed on a fine toothing (10b) and the internal toothing formed by in the outer rotor (9), rotatably mounted, also a fine toothing (11a) having planetary rotors (11).
