Abstract: A nuclear low pressure packing casing having reduced horizontal joint leakage. This is accomplished by providing packing ring carriers that are separately formed from the casing so that thermal distortion loads will not be transmitted to the horizontal joints. In an embodiment of the invention, the packing ring carriers are fit in place in pre-machine grooves in the casing rather than being welded directly to the casing. According to further, optional feature of the invention, the vent or seal steam enters or exits at only one of the bottom quadrants rather than the entire bottom half so that the packing case design can be simplified to reduce fabrication and material costs.

Abstract: Axially spaced, pressure-energized seals in a sealing assembly are carried in a conventional seal assembly housing. The seals surround a rod that reciprocates through the housing to power a fluid pump. The seals are pressure-energized by a flowable sealant that is injected through the housing into a confined annular area defined between the seals. The sealant maintains worn seals in close sealing engagement with the reciprocating rod to prevent fluid or pressure loss from the pump. The sealant pressure resists the repeated flexing stresses exerted by the axial rod movement to minimize seal fatigue wear. Components of the seal assembly may be split to permit seal repair or replacement without requiring the removal of the rod from the assembly. The pressure and composition of the flowable, injectable sealant cooperate with the split seal assembly components to prevent leakage across the seal component splits.

Abstract: Guide for the piston rod of a piston-cylinder assembly, especially for a vibration damper, a shock-absorbing strut, or a level-control device. The guide has a guide body with an outer end surface holding a piston rod seal, where the piston rod is installed in the guide and sealed with freedom to move in the axial direction. The piston rod seal has an axial extension opposite the piston-cylinder assembly, which extension is held in an annular recess in the end surface, which recess is spaced from the piston rod and coaxial to the piston rod.

Abstract: The faying surface of one or of both of a pair of substrates is provided with a layer of solid polyurethane sealant which is adherent to at least one of the respective surfaces. The substrates are additionally fastened together so that the faying surfaces compress the polyurethane sealant between them to form a fluid seal across the entire spacing between the two surfaces, and between the polyurethane sealant and the faying surfaces themselves.

Abstract: An improved seal arrangement in an assembly such as a valve assembly in which a compression member is provided to press a seal between the compression member and the valve body. In a preferred form, the compression member includes a recess which receives a first portion of the seal, and a second portion of the seal is disposed between the compression member and the valve body. In addition, a first inclined surface is provided in the recess of the compression member. The first inclined surface contacts a second inclined surface provided on the first portion of the seal. A third inclined surface on the compression member contacts a fourth inclined surface provided at a juncture between the first and second portions of the seal. Further, a fifth inclined surface is provided on the housing to contact a sixth inclined surface provided on the second portion of the seal. The arrangement creates lateral or side loads between the seal and the valve stem and also between the seal and the valve body to prevent or minimize leakage over a large number of valve operating cycles.
