Abstract

Der Erfindung betrifft eine Innenzahnradpumpe mit einem innenverzahnten Hohlrad (2) und einem damit kämmenden Ritzel (3), bei der in dem sichelförmigen Raum zwischen diesen beiden Rädern ein Füllstück (8) eingesetzt ist. Um ein Flattern des Füllstücks (8) und die damit verbun­ denen Geräusche zu vermeiden wird vorgeschlagen, das Füllstück (8) mittels vom Druckraum (D) in eine Nut (12) in der einen Planseite geleitetes Drucköl mit der ande­ ren Planseite gegen das Pumpengehäuse (1) zu pressen. Mittels eines ebenfalls vom Drucköl beaufschlagten Druck­ stückes kann das Füllstück (8) auch in der Drehrichtung (6) arretiert werden.
