<p>A hydraulic piston machine (1) is disclosed, having a cylinder body (2), which has at least one cylinder (5), in which a piston (6) is arranged to move back and forth and bears by way of a slide shoe (9) against a control surface, and having a pressure plate (15) which holds the slide shoe (9) in engagement with the control surface (14). It is desirable to be able to operate such a machine also with a fluid that has no or only poor lubricating properties. To that end, the pressure plate (15) and/or the control surface (14) is provided with a layer (21, 26) of a friction-reducing plastics material at least in one of the regions with which in operation they rub against other parts (9, 17).</p> |
