Abstract
The invention relates to an axial piston machine (,) comprising a housing (,), a drive shaft (,) mounted in a rotational manner in the housing (,) around a drive shaft axis (,), a cylinder drum (,) which is connected to the drive shaft (,) in a non-rotational manner and in which are embodied cylinders (,) for receiving axially movable pistons (,), and a control plate (,) with control openings (,) designed to cyclically connect the cylinders (,) with a high-pressure and a low-pressure line. The invention provides for a pressing device with at least one centrifugal body (,), which is impinged upon by a centrifugal force (F,) that increases with the number of rotations per minute (n) of the cylinder drum (,). The invention also provides for a force deflection unit (,) designed to transform the centrifugal force (F,) acting on the centrifugal body (,) into a force acting against the cylinder drum (,), whereby said force has a component (F,) which is aligned towards the control plate (,) and in an axial position in relation to the drive shaft axis (,).
