Abstract
Die Erfindung betrifft eine volumenstromvariable Rotorpumpe (1) mit einem einen Sauganschluss (3) und einen Druckanschluss (4) aufweisenden Pumpengehäuse (2), mit einem in einem Stellglied (7) aufgenommenen Außenrotor (9) und mit einem exzentrisch im Außenrotor (9) angeordneten, antreibbaren Innenrotor (10) mit Außenverzahnung (10a), wobei die Zähnezahl der Außenverzahnung um eins größer als die der Innenverzahnung ist, die Innen- und die Außenverzahnung miteinander in Eingriff stehen und der Volumenstrom durch eine Lageveränderung des Stellgliedes (7) veränderbar ist. DOLLAR A Es wird vorgeschlagen, dass der Außenverzahnung (10a) eine Feinverzahnung (10b) überlagert ist und die Innenverzahnung durch im Außenrotor (9) aufgenommene, drehbar gelagerte, ebenfalls eine Feinverzahnung (11a) aufweisende Planetenrotoren (11) gebildet ist.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).
