Abstract

Die Erfindung betrifft eine Sperrflügelpumpe, mit einem einen Rotor aufnehmenden Gehäuse, in dessen Wandung mindestens eine einen Sperrflügel aufnehmende Nut eingebracht ist, der durch eine Feder gegen die durch Trennbereiche voneinander getrennte Steuerflächen aufweisende Umfangsfläche des Rotors angedrückt wird und der durch eine Drehbewegung des Rotors Räume mit variablen Volumina voneinander abgrenzt, wobei ein in Drehrichtung vor dem Sperrflügel liegender Raum mit einem Druckauslaß und ein in Drehrichtung nach dem Sperrflügel liegender Raum mit einem Saugeinlaß verbunden ist.The invention relates to a vane pump, with a rotor receiving housing, in the Wall at least one receiving a locking wing Groove is introduced by a spring against the control areas separated from each other by separation areas having peripheral surface of the rotor pressed and that by rotating the rotor spaces differentiated from each other with variable volumes, whereby one in the direction of rotation in front of the locking wing Room with a pressure outlet and one in the direction of rotation after the blocking wing room with a suction inlet connected is.

Es ist vorgesehen, daß dem Saugeinlaß (44) eine Drosselstelle (61) und dem Druckauslaß (42) eine druckabhängige Schließ- bzw. Öffnungseinrichtung zugeordnet ist.
