Abstract

Die Erfindung betrifft eine Innenzahnradpumpe mit Hohlrad, Ritzel und Füllstück aus Dichtsegment und Segmentträger. Zwischen Dichtsegment und Segmentträger ist ein Druckraum ausgebildet. Zur Verringerung der Druckpulsationen am Füllstück wird neben einer Steuernut, die sich zwischen dem Druckraum und einer zweiten Zahnlücke im Hohlrad erstreckt, eine Zusatznut zwischen Druckraum und einer ersten Zahnlücke im Hohlrad vorgesehen.
