Abstract: A rubber plug includes a seal portion and an extension portion. Inner and outer peripheral lips form respective water-tight seals between the rubber plug and a cavity, and the rubber plug and a wire. The extension portion extends from the seal portion toward an open end of the cavity. When a bending force acts on the wire, the extension portion slightly deforms elastically, Put the seal portion will not be deformed. Therefore, the water-tight condition between the cavity and the wire is maintained. Therefore, even when a bending force acts on the wire, water is prevented from intruding into the cavity.

Abstract: A stripper for a threaded spindle has an essentially ring-shaped body, the inner circumference of which is provided with an internal screw thread (12) that works in cooperation with the carrier screw thread of the threaded spindle. The internal screw thread (12) has at least one recess (14) which is open towards the surroundings of the stripper and which interrupts at least one thread. At least one side edge of the recess (14) runs essentially cross-wise to the threads and is configured as a stripping edge (18), and the screw thread area (16) which carries the stripping edge (18) can be pressed into the carrier screw thread by means of a predetermined force. As a result of this stripper configuration, the topmost layer of the residual film of grease and the abrasive dust found on it can be accurately peeled off, even from the low part of the profile, so that layers of grease that are always clean lie at the points of contact between the shaft bush and the threaded spindle.

Abstract: A fluid handling machine having a shaft, a radially disposed housing, and a backup seal. During normal operation, the backup seal is concentric with and radially spaced from the shaft. The backup seal includes a first annular portion located adjacent the backup seal chamber and a second annular portion preferably made of carbon graphite. The backup seal is configured to engage the housing such that when the fluid pressure in the backup seal chamber exceeds a predetermined level, a sufficient axial force is applied to the first annular portion and transmitted therethrough to the second annular portion to cause the second annular portion to close radially into sealing engagement with the shaft.

Abstract: A slide ring seal assembly includes first and second machine components each having an annular clamping face coaxial with the rotary axis of the assembly; and first and second slide rings including respective inner and outer peripheral clamping faces each surrounding the assembly axis. The slide rings together define an annular sliding surface surrounding the assembly axis. First and second elastic sealing rings are compressed between the respective clamping faces of the machine components and the slide rings. The first sealing ring and the clamping face of the first machine component together define a first sealing area and the second sealing ring and the clamping face of the second slide ring together define a second sealing area. Each sealing area is bordered by a boundary line distal from the annular sliding surface and by a boundary line proximal to the annular sliding surface.

Abstract: A shaft sealing ring comprising an annular holder (3) and an annular sealing section consisting of a sealing lip (4) extending to the surface (1) of the shaft against the pressure difference to be sealed and a radially extending connecting section (15) connecting the sealing tip (4) to the holder (3). The sealing tip (4) and the connecting section (15) are dimensioned so that their flexions to be expected under the pressure difference to be sealed exert a contrary affect upon the angle at which the sealing ring (4) is seated on the surface (1) of the shaft. This is made possible by the fact that at least one part (8) of the connection section (15) which is closer to the shaft surface (1) than another part (7) of the connection section (15) is deformed further towards the low-pressure side (PN) under the pressure difference to be sealed than the other part (7) of the connecting section.

Abstract: A face seal includes an annular carbon stator having a flat surface in rubbing contact with the flat surface of a composite annular rotor. The annular rotor has a head portion and a base portion. Embedded in the head portion are high thermal conductivity graphite fibers that are oriented to maximize heat dissipation. Incorporation of graphite fibers makes the rotor resistant to time-dependent creep deformation, thus preserving sealing integrity.

Abstract: A method for assembling a pipe joint including an inner pipe having an outside surface and an outer pipe having an annular groove for receiving a gasket and a pipe joint gasket used in that method. The gasket includes front and back regions, the front region being resilient and relatively rigid, the back region being softer and more resilient than the front region. An interior tip of the back region sealingly engages the inner pipe outside surface and spaces the inner pipe from the front region while the inner pipe is being inserted. The exterior tip of the back region in cooperation with the front and back regions, both secures and seals the front and back regions to the annular groove before inserting the inner pipe. The gasket is displaced by the inserted inner pipe which exerts pressure on both pipes thus sealing the annulus between the pipes. The gasket is further displaced by internal pipe pressure or external pressure which exerts proportionally greater sealing force on both pipes.

Abstract: A sealing member for sealing between a rotating surface (12) and a stationary cylindrical surface (13). The sealing member (8) is sealing engaged to the rotating surface (12) and is so constructed that) at a rotational speed greater than a predetermined speed of rotation of the rotating surface, the seal lip (27), due to centrifugal force, disengages from the stationary cylindrical surface (13) and, at or below the predetermined speed of rotation, sealingly engages the stationary cylindrical surface (13).

Abstract: A sealing connection between first and second members having coacting telescoping ends. A resilient U-shaped metal seal ring is positioned in a groove in the first member and seals against both the first and second members and includes a soft metallic seal coating. Projections extend from the seal on each side of the soft coating for protecting the coating as the members are engaged. Recesses are provided in the second member for receiving the projections and allowing the metallic seal to engage the second member. A transitional surface on the end of the second member engages the projection means for compressing the metal seal as the members are engaged.

Abstract: A metal seal has features that make it particularly useful for wide temperature variations of the fluid flowing through the conduits that it seals. The seal ring locates within a groove in the face of each conduit. The seal ring engages the outer wall of the grooves. The seal ring has inner legs that engage the inner wall of the grooves. The legs are separated from a mid-section of the seal ring by a slot. The radial width of the seal ring is greater than the distance radially across the grooves so as to provide an interference fit. The deformation of the seal is elastic, not permanent. The sealing surfaces are cylindrical or conical. The seal is not axially compressed.

Abstract: A gasket (10) seals an interface between a pair of parts (12, 14) mounted to each other in torqued engagement and having facing surfaces (20, 22) thermally expanding towards each other upon heating, and contracting away from each other upon cooling. The gasket includes a resilient member (11) between the engaging the facing surfaces in sealing relation, and a plurality of rigid spacers (36, 38, 40, 42, 44, 46) permitting torqued engagement of the parts without squeezing out the resilient member from between the facing surfaces, and preventing compression of the resilient member beyond its permanent deformation elastic limit upon thermal expansion of the facing surfaces towards each other upon heating, including central portions (56, 58) of the facing surfaces thermally warping between spacers. Upon cooling, the facing surfaces contract away from each other, and the resilient member recovers and expands to maintain the seal against the facing surfaces.

Abstract: A seal assembly having a backup ring through which a piston reciprocates. There is a seal sleeve made of a non-abrading, extrusion resistant material that surrounds the piston at a location forwardly of the backup ring.
