ABSTRACT:
A hydraulic axial piston machine (1) is disclosed, having a cylinder drum (2) which is mounted rotatably in a housing and comprises at least one cylinder (3) which, on rotation of the cylinder drum (2), passes over control kidneys (15) in a control face. In order to be able to operate such a machine even with hydraulic fluid that has no or only slight lubricating properties, such as, for example, water, and in order to be able to manufacture the machine with few manufacturing steps, the control face is located on the rear flange (9) of the housing, and the control kidneys (15) are formed in a plastics material insert (10) which is arranged in the rear flange (9) of the machine (1).
