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.
