Abstract

Die Erfindung betrifft eine Verdrängerpumpe mit variablem Fördervolumen, insbesondere eine einhubige Flügelzellenpumpe zur Erzeugung eines Druckmittelstroms zu einem Verbraucher, mit einem von einer Wandung (22) umgebenen und freigängig gehaltenen Kurvenring (6). Zur Veränderung des Fördervolumens ist der Kurvenring (6) zu einem Rotor (4) verschiebbar. Zur Beeinflussung der Position des Kurvenrings (6) ist ein Federelement (18) vorgesehen, welches in einer Vertiefung (17) der Wandung (22) angeordnet ist.

The invention relates to a displacement pump with a variable delivery volume, in particular a single-stroke vane pump for generating a pressure medium flow to a consumer, with one of a wall (22) surrounded and freely held cam ring (6). To change the delivery volume of the cam ring (6) to a rotor (4) is displaceable. To influence the position of the cam ring (6), a spring element (18) is provided, which is arranged in a recess (17) of the wall (22).
