Abstract: A high pressure sealing arrangement of the type in which a rotor sealing ring end face generates a gas pressure with a stator sealing ring end face at a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness. The gap width is less than 0.4 mm and preferably less than 0.3 mm. The sealing O-ring additionally serve as a compensation or centering ring and has a material hardness which is greater than the extrusion threshold of this material through the gap and is less than a hardness of 90 Shore A according to German Industrial Standard DIN 53505. Preferably the hardness of the O-ring is less than 80 Shore A under this Standard.

Abstract: A high pressure sealing arrangement of the type in which a rotor sealing ring end face defines a gas pressure with a stator sealing ring end face has a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness. The polar or geometric moment of inertia of the stator sealing ring is sufficiently large that the gap width of the functional annular gap between the shaft-side cylindrical part of the sealing ring in the operational state and under the operational differential pressure corresponds to the structurally predetermined gap width of the mounting ring gap between the cylindrical part of the sealing housing and the stator sealing ring in all operational states and is less than 0.4 mm and preferably less than 0.3 mm.

Abstract: A turbocompressor shaft seal, especially for a high-pressure turbocompressor, has each of its gas-side and atmosphere-side slide rings biased toward a rotor ring of the shaft and associated with blocking-liquid compartments which are interconnected by an annular passage aroung the rotor ring. The compartments are connected in a closed circulation path with a circulating pump and a cooler and leakage liquid is returned by a feed pump to the liquid circulation with the aid of a pressure transformer biased on one side by the gas pressure to be sealed and an adjustable spring force and, on the other side, by the pressure of the blocking liquid. The surface area ratio K between the area of the atmosphere-side slide ring biased by the blocking liquid pressure toward the rotor ring and the sealing area of the atmosphere-side slide ring is substantially 0.45 to 0.60, the thermal conductivity of the slide rings and rotor rings is greater than 250,000 N/mm.sup.

Abstract: A high pressure sealing arrangement of the type in which a rotor sealing ring end face defines a gas pressure with a stator sealing ring end face has a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness. The conditions are such that torsional deformation of the stator sealing ring is practically zero under all operating conditions so that the recesses, grooves or the like of the end faces or at least one of them need not be defined to provide a twist-restoring force by reason of the pressure in the sealing gap.

Abstract: The invention concerns a sliding body for sliding systems in which sliding surfaces of sliding and counter components form a gap in which there is a fluid, whereby the sliding body (1) at least in the area of sliding surfaces (10) is comprised of several stacked thin form elements stamped out of foils or cards, which are solidly bonded together on the contact faces. The invention also concerns a process for the production of the sliding body, whereby foils are produced from ceramic slips, in which various hollow chambers and/or recesses are stamped or impressed, a laminating agent is applied to the foils or cards, the foils or cards are stacked into a sliding body packet and the layers of the stack are laminated together, the organic components are partially baked off, after which a post-treatment of the sliding body takes place, then the remainder of the organic components are removed, and then the laminated sliding body is sintered between 1200.degree. and 2200.degree.
