PCT No. PCT/DK93/00443 Sec. 371 Date May 31, 1995 Sec. 102(e) Date May 31, 1995 PCT Filed Dec. 23, 1993 PCT Pub. No. WO94/16217 PCT Pub. Date Jul. 21, 1994A hydraulic machine with a piston and slider shoe unit (1) is disclosed, in which the piston (2) and the slider shoe (3) are joined to one another by way of a ball-and-socket joint (4) forming a first contact surface, and the slider shoe (3) lies via the intermediary of a second contact surface on a control surface (9), a friction-reducing layer being arranged on one contact surface. It is desirable for a hydraulic machine of the that kind to be capable of reliable operation even when using hydraulic fluids having only a operation even when using hydraulic fluids having only a poor or no lubricating effect at all, yet to be inexpensive to manufacture. For that purpose, the friction-reducing layer (11) is extended to at least one further contact surface. |
