The invention relates to an axial piston machine () comprising a housing () in which a drive disk () and a cylinder block () axially disposed next to it are received so as to be rotatable relative to each other about longitudinal center axes (). These axes run obliquely at an angle (W) relative to each other in an oblique axis plane (E). A cam disk () is disposed on the front of the cylinder block () facing away from the drive disk () and is supported on the housing () by means of a positioning device () with positively engaging positioning elements (). A guide element () having a guide center axis () running coaxially to the longitudinal center axis () of the cylinder block () is disposed on the side facing the cylinder block (). In order to provide for a simple construction and to allow for a step-wise modification of the throughput, the positioning element () disposed on the cam disk () is set off in the oblique axis plane (E) at an angle to the guide center axis (). The cam disk () can be mounted in a second position, rotated relative to the guide center axis () by approximately 180&#xb0;, in which the positioning elements () are also functionally linked.

Axial piston machine with offset positioning element and cam disk for such an axial piston machine

The invention relates to an axial piston machine having an oblique disk body (14) arranged in a housing (1) in a torsionally secure manner, having a drive shaft (4), which is mounted in the oblique disk body (14), and having a rotatable cylinder drum (7), which is coupled with the drive shaft (4) and in which a plurality of pistons (9) may be displaced axially in piston bore holes, their piston heads (11) being supported by means of sliding shoes (12) against the oblique surface (13) of the oblique disk body (14). The purpose of the invention is to construct the axial piston machine in such a way as to make possible torsional securement of the oblique disk body (14) which is simple in terms of production techniques and assembly, with a compact constructional form. This is achieved by mounting the oblique disk body (14) with its peripheral surface (16, 17) torsionally secured in a form-locking manner in a recess (19) of the housing (1) shaped to correspond to the peripheral surface (16, 17).
