Abstract

Die erfindungsgemäße Axialkolbenmaschine weist eine Steuerplatte (1) und eine Zylindertrommel auf. Die Steuerplatte (1) weist eine erste und zweite Steueröffnung (2) und (3) auf zwischen denen sich jeweils ein Umsteuerbereich (4) und (5) befindet. Die Zylindertrommel ist bezüglich der Steuerplatte (1) drehbar und weist mindestens einen Zylinderraum auf, der unter Drehung der Zylindertrommel über eine Zylinderöffnung (7) abwechselnd mit der ersten und zweiten Steueröffnung (2) und (3) verbunden ist. Zusätzlich weist die Axialkolbenmaschine ein Speicherelement (10) auf, das mit einem Umsteuerbereich (5) verbunden ist. Das Speicherelement (10) ist als Zylinder mit einem bewegbaren Kolben (12) ausgebildet, wobei auf der von der Zylinderöffnung (7) abgewandten Seite des Kolbens nur die Federkraft oder nur die Federkraft plus eine Druckkraft wirkt. Die Druckkraft entsteht dabei nur durch den Druck der Hochdruckseite 3 auf eine reduzierte Querschnittsfläche des Kolbens 12.
