PCT No. PCT/DK95/00269 Sec. 371 Date Dec. 23, 1996 Sec. 102(e) Date Dec. 23, 1996 PCT Filed Jun. 27, 1995 PCT Pub. No. WO96/01947 PCT Pub. Date Jan. 25, 1996A piston with a slide shoe for a hydraulic piston engine, where the slide shoe comprises a ball socket, and where the piston is arranged with a corresponding ball head, whereby these are joined in a ball-and-socket joint, and where at least partially the ball head is constituted of a spherical surface of a friction reducing material moulded onto and retained in relation the piston. As a consequence of the subsequent shrinking of the moulded-on, friction reducing material, a possibility is obtained of good fixation of the ball head on the piston, while at the same time a gap can be created between the ball socket and the ball head. |
