Abstract
Die Erfindung betrifft eine Axialkolbenmaschine (1) mit einer um eine Zylindertrommelachse (7) drehbar gelagerte Zylindertrommel (6), in der Zylinderbohrungen (10) ausgebildet sind, in welchen Kolben (11) verschiebbar geführt sind. Die Axialkolbenmaschine (1) weist ferner eine Anschlußplatte (26), in welcher eine Niederdruck-Anschlußöffnung (60) und eine Hochdruck-Anschlußöffnung (61) ausgebildet sind, sowie eine Steuerscheibe (25) auf. In der Steuerscheibe (25) sind Steueröffnungen (27, 28) ausgebildet, um die Zylinderbohrungen (10) der um die Zylindertrommelachse (7) rotierenden Zylindertrommel (6) zyklisch mit der Niederdruck-Anschlußöffnung (60) und der Hochdruck-Anschlußöffnung (61) zu verbinden.The invention relates to an axial piston machine (1) with one Cylinder drum axis (7) rotatably mounted cylinder drum (6) in which Cylinder bores (10) are formed, in which pistons (11) are slidably guided are. The axial piston machine (1) also has a connecting plate (26) in which a Low pressure connection opening (60) and a high pressure connection opening (61) are formed are, as well as a control disc (25). There are control openings in the control disk (25) (27, 28) formed around the cylinder bores (10) around the cylinder drum axis (7) rotating cylinder drum (6) cyclically with the low pressure connection opening (60) and the high pressure connection opening (61) to connect.
Ferner ist eine Fixiereinrichtung vorgesehen, um den Verdrehungswinkel (α), der die Steuerscheibe (25) gegenüber der Anschlußplatte (26) einnimmt, zu fixieren. Erfindungsgemäß umfaßt die Fixiereinrichtung zumindest einen von der der Steuerscheibe (25) abgewandten Seite der Anschlußplatte (26) zugänglichen, außerhalb der Anschlußöffnungen (60, 61) gelegenen Fixierstift (43). Der Fixierstift (43) fixiert die Steuerscheibe (25) gegenüber der Anschlußplatte (26) und legt somit den Verdrehungswinkel (α) zwischen der Steuerscheibe (25) und der Anschlußplatte (46) fest. Furthermore, a fixing device is provided in order to fix the angle of rotation (α) which the control disk (25) makes with respect to the connection plate (26). According to the invention, the fixing device comprises at least one fixing pin (43) which is accessible from the side of the connecting plate (26) facing away from the control disk (25) and is located outside the connecting openings (60, 61). The fixing pin (43) fixes the control disc (25) relative to the connection plate (26) and thus defines the angle of rotation (α) between the control disc (25) and the connection plate (46).
