Abstract

Bei einer Flügelzellenpumpe (1), deren zylindrischer Rotor (5) einen einzigen, in einer Axialebene des Rotors (5) liegenden Führungsschlitz besitzt und bei der der Rotor (5) die im Normalschnitt als Kreiskonchoide ausgebildete Gehäuseumfangswand längs einer Mantellinie berührt, wird der Verschleiß an den Flügeln (7) dadurch gemindert oder vermieden, daß dem im Gehäuse (2) auskragend gelagerten Rotor (5) in dem der Lagerseite gegenüberliegenden Gehäusedeckel (4) eine in diesem frei drehbar gelagerte Kurbel (10/13) gegenüberliegt. Diese wirkt mit dem Rotor (5) zusammen und weist an ihrem freien Ende einen außermittig gelagerten Zapfen (10) auf, der in die Längsmitte (15) des Flügels eingreift. Hierdurch werden die bei der Rotordrehung am Flügel (7) auftretenden Zentrifugalkräfte teilweise durch die Kurbel (10/13) aufgenommen. In a vane pump (1), the cylindrical rotor (5) a single one, in an axial plane of the rotor (5) has lying guide slot and in which the rotor (5) the one trained as a circular conchoid in normal section If the circumferential wall of the housing is touched along a surface line, the Wear on the wings (7) reduced or avoided that the rotor is cantilevered in the housing (2) (5) in the housing cover opposite the bearing side (4) a crank which is freely rotatably mounted therein (10/13) opposite. This interacts with the rotor (5) and has an eccentrically mounted at its free end Pin (10) on, in the longitudinal center (15) of the wing intervenes. This will cause the rotation of the rotor on Wing (7) occurring centrifugal forces in part by the Crank (10/13) added.
