Abstract

Eine Axialkolbenmaschine (1) weist eine Zylindertrommel (3) auf, in welcher Zylinderbohrungen (4) zur Aufnahme von Kolben (5) vorgesehen sind. Die Zylinderbohrungen (4) stehen über Zylinderöffnungen (15) mit einer Steuerscheibe (8) in Verbindung. In der Steuerscheibe (8) sind eine Niederdrucköffnung (19), eine Hochdrucköffnung (18) und eine Mitteldrucköffnung (23) vorgesehen. Die Mitteldrucköffnung (23) ist in Drehrichtung (38) der Zylindertrommel (3) in bezug auf die Steuerscheibe (8) zwischen einer ersten Totpunktlage (21), an welcher sich die axiale Bewegungsrichtung der Kolben (5) umkehrt, und der Hochdrucköffnung (18) angeordnet. Ferner ist eine Regeleinrichtung (24, 32) vorgesehen, die den Druck an der Mitteldrucköffnung (23) auf einen vorgegebenen Mitteldruck (MD) zwischen dem an der Niederdrucköffnung (19) herrschenden Niederdruck (ND) und dem an der Hochdrucköffnung (18) herrschenden Hochdruck (HD) einregelt.
