Abstract: A hydraulically-operated support device for semitrailers is disclosed comprising a hydraulic cylinder semitrailer support and a pump subassembly having three independently operable pumps for generating and controlling the hydraulic operating pressure. The hydraulic cylinder semitrailer support has an extending piston in an extending cylinder, in the bottom end of which is formed a load-raising cylinder for a load raising-piston. A first annular space is formed between the extending piston and the extending cylinder and a second annular space is formed between the load-raising piston and the load-raising cylinder. The annular spaces allow application of pressure in the retraction direction. The pump subassembly comprises an extending pump acting on the extending piston, a load-raising pump acting on the load-raising piston and a retracting pump acting on the annular spaces. The transmission ratio between the load-raising pump and the load-raising piston is substantially lower than the transmission ratio between the extending pump and the extending piston.

Abstract: A trailer coupling is provided with a sliding plate and a coupling plate having an anti-friction layer, preferably of a PTFE composite material. To make it possible that in operation the anti-friction surface always remains paired with the same counter surface so that they may matingly wear with each other, a steel plate is placed onto the king journal of the tractor covering the slide plate itself. The steel plate is finished to a depth of roughness of 1 .mu.m. The bore of the steel plate permits passage of the king journal without additional clearance, so that the steel plate is maintained in position by tilting and no further connection is necessary between the steel plate and the slide plate.

Abstract: A guide ring having a seating surface of `U`-shaped cross-section. A plurality of the guide rings may be carried by a piston, piston rod or the like in abutting relation to provide a continuous imperforate surface, or axially spaced from one another with a sealing member interposed between adjacent rings, the sealing member being biased into its operative position by fluid pressure. A ring of resilient material is positioned radially inwardly of the rings and sealing member and is provided with chamfered surfaces which are acted on by biasing means. A sealing arrangement is also provided comprising ring seals and/or stripper rings disposed in a groove in a piston or piston rod and formed of soft material with a lip seal in contact with a surface to be sealed. A shaped sliding ring of abrasion-resistant material which bears on the surface to be sealed is disposed in the ring seal and/or stripper ring.
