摘要： A high-pressure sealing arrangement is provided for sealing a gap (26) between two concentric machine parts (4, 5) which can be moved relative to each other, of which a first machine part (4) comprises a groove (3) and a second machine part (5) comprises an outer peripheral surface (7) opposite the groove (3). A sealing ring (1) of an extrusion-resistant material and a tensioning ring (2) of an elastomeric material are provided in the groove (3). A shaped section of the sealing ring (1) on the low-pressure side can be deflected towards the outer peripheral surface (7) under fluid pressure load. When the pressure decreases, the pressure-dependent deflection of the sealing ring (1) automatically returns towards the initial, unpressurized state of the sealing ring (1). The sealing ring (1), viewed in cross-section and in the unpressurized state, has a shaped sealing ring surface (6) facing the outer peripheral surface (7), which merges at least with respect to the shaped section on the low-pressure side, into a shoulder surface (13) separated from the outer peripheral surface (7) at a first separation d1, which merges into a shoulder surface (13) side surface (20) with a second, larger separation d2 from the outer peripheral surface (7).

摘要： A magnetic bearing isolator assembly. The assembly comprises first and second body parts, a ferromagnetic ring and a plurality of magnets received in spaced apart pockets. The first body part has a circumferential groove for receiving a ring of a ferromagnetic material. A radially outer groove in the first body part accommodates the second body part which has an outer, frusto-conical surface which is very slightly larger than the diameter of the smaller axial surface on the first part. The first and second parts are made from a composite fluorocarbon-carbon-graphite material with substantial glass filling therein.

摘要： A structure and method of manufacturing an outer surface of a shaft avoids the creation of a preferential lead and thereby minimizes leakage through an annular seal assembly when such shaft is rotated or otherwise moved relative thereto during use. The outer circumferential surface of the shaft is formed having a plurality of relatively small irregularities that are evenly distributed thereabout. Such irregularities may be defined by relatively higher portions and relatively lower portions that are formed in an intersecting, cross hatched pattern or in a circumferentially extending undulating or oscillating pattern. To form the cross hatched pattern, an apparatus can be operated to engage the outer circumferential surface of the shaft in two sequential passes in opposite axial directions while the shaft is being rotated. To form the undulating pattern, an apparatus can be operated to engage the outer circumferential surface of the shaft in an axially reciprocating manner while the shaft is being rotated. By varying the feed rate of the apparatus, the rotational speed of the shaft, and the magnitude of the force applied by the apparatus against the outer circumferential surface of the shaft, the size, shape, and depth of the surface irregularities can be varied as desired.

摘要： A seal assembly for a reciprocating shaft includes a body having a bore and a shaft adapted to move reciprocally within the body between an extended position extending from the body and a retracted position retracted within the body. The shaft has a first seal travel area which is in contact with a first seal during axial reciprocating movement of the shaft. The shaft has a second seal travel area which is in contact with a second seal during axial reciprocating movement of the shaft. The first seal travel area and the second seal travel area are axially spaced separate and distinct areas on the shaft. Damage to the exposed portion of the first seal travel area leading to a failure of the first circumferential seal, does not lead to failure of the second circumferential seal.
