ABSTRACT:
An axial-piston machine such as an axial-piston motor or, preferably, an axial-piston pump, has a cylinder drum rotatable in a chamber defined by the machine housing, the cylinder bores at low pressure communicating with the interior of the housing. Only part of the end of the cylinder drum turned toward a displacing slide covers the surface of this slide which is provided with an arcuate groove for communication with the cylinder bores under elevated pressure while the control surface of this slide only covers the high-pressure portion of the surface of the cylinder drum so that the latter overhangs the slide.
