Diese Innenräume sind von beiden Seiten her über je ein Gehäusedeckel abgeschlossen. In den jeweiligen beiden Teilräumen (Innenraum) ist je ein Hubring gelagert, welche beide über mindestens eine Lagerwelle miteinander verbunden sind.

abgesehen davon, daß noch keine Angaben über den Förderstrom

darin, daß die hydrostatische Radialkolbenmaschine nicht
von zwei Rotoren 18, 19 auf einer Welle als Lager ausgeht,
sondern von einer Achse 43, auf der die beiden Rotoren
leicht drehbar gelagert sind, so daß ein asynchrones Arbeiten
