Abstract

Die Erfindung betrifft eine Zahnradpumpe mit Fördermegenregelung, die eine die Fördermenge verändernde Verschiebeeinheit (7) aufweist, die zwischen einer ersten (10) und einer zweiten (11) Druckkammer verschiebbar angeordnet ist, wobei die zweite Druckkammer (11) eine zusätzlich auf die Verschiebeeinheit (7) wirkende Druckfeder (9) aufweist. Sie löst die Aufgabe, den Bauraum einer derartigen Zahnradpumpe zu verringern und damit auch deren Gewicht zu reduzieren. Dazu ist die erste Druckkammer (10) über ein Regelventil (12) mit der zweiten Druckkammer (11) verbunden, das über einen mit der Druckkammer (10) verbundenen Druckumwandler (13) mit einem mit diesem gekoppelten Steuergerät (14) mit einem entsprechenden Kennfeld wirkverbunden ist.
