Abstract

A hydraulic piston machine is disclosed, having arranged in a basic body (1) at least one cylinder (2) in which a bushing made of a plastics material is arranged. Securing the bushing in the basic body occasionally presents problems which render manufacture of the machine more difficult. The present invention is intended to simplify the manufacture of the piston machine. To that end, the external diameter of the bushing (3) and the internal diameter of the cylinder (2) are matched to one another to provide freedom from play and the plastics material has a substantially smaller modulus of elasticity than the basic body (1).
