Abstract

Die Erfindung betrifft eine Innenzahnradmaschine mit den folgenden Merkmalen:
- im sichelförmigen Raum ist ein Füllstück angeordnet, das zwei Bereiche unterschiedlicher Drücke gegeneinander abgrenzt;
- das Füllstück ist unterteilt in ein ritzelseitiges Teil, das an den Ritzelzähnen anliegt, und in ein hohlradseitiges Teil, das an den Hohlradzähnen anliegt.
Um ein Flattern der Füllstückteile zu verhindern ist eine leitende Verbindung vorgesehen, die sich zwischen Zahnlücken des Hohlrades und Zahnlücken des Ritzels erstreckt und die im Bereich des Füllstückes angeordnet ist.
