Seal Between Fixed Parts Or Static Contact Against Relatively Movable Parts Patents (Class 277/590)
  • Patent number: 6161839
    Abstract: The invention is a valve seal assembly (43) illustrated in the context of a compressor bleed valve (36) for a gas turbine engine. The seal assembly includes a seal carrier (44) having a circumferentially extending groove (72) bordered by a pair of opposing flanges (74). The flanges cooperate to define a recess (76) portion of the groove and a throat (78) portion of the groove. The seal assembly also includes one or more seal elements (46) each having a base (82), conformal with the recess, and longitudinally captured in the recess by the flanges. A stem (84) extends from the base and projects through the throat, and a sealing bead (86) extends from the stem. An insert (88) extends circumferentially in the base for stiffening the base about a circumferential bending axis (C). An access port (96) facilitates installation and removal of the seal elements (46) and a cover (98) traps the seal elements in the carrier (44).

  • Patent number: 6152453
    Abstract: In the inner portion of a spherical annular seal member (55) extending from a cylindrical inner surface (52) to an outer surface (53) formed in the shape of a partially convex spherical surface, a heat-resistant sheet member (3) having a heat-resistant coating (2) on overall surfaces of a heat-resistant sheet and a reinforcing member (9) constituted by a metal wire net (8) are compressed and intertwined with each other, and are thus arranged to be provided with structural integrality. The outer surface (53) formed in the shape of the partially convex spherical surface is constituted by an exposed surface of an outer surface layer (56) formed of the heat-resistant coating (2), and the reinforcing member (9) constituted by the metal wire net (8) formed integrally with the outer surface layer (56) is disposed in the outer surface layer (56).

  • Patent number: 6129359
    Abstract: The sealing assembly for a port of a valve or the like is disclosed. In detail, the sealing assembly includes the port having a circular shaped end with a circular shaped knife-edge thereon. The sealing assembly further includes a hollow cap having a closed first end with an aperture therethrough and an open second end. The cap further includes internal threads adapted to mate with the external threads of the port. A gasket is mounted within the cap having flat first and second principle sides and made of a deformable metal, the first principle side of the gasket for mounting against the circular shaped knife edge of the port. A plunger having a circular shaped disc portion is adapted to fit within the hollow cap and is engagable with the first principle surface of the gasket and includes a shaft portion extending out of the aperture. The cap and shaft of the plunger include external wrenching flats.

  • Patent number: 6113109
    Abstract: A cylinder head gasket has at least one combustion opening, a central metallic core and an expanded graphite facing layer on each side of the core. A stress rising bead is disposed on at least one of the graphite layers encircling each combustion opening for sealing around the combustion openings.

  • Patent number: 6093467
    Abstract: A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding.

  • Patent number: 5833243
    Abstract: A seal for a constant velocity joint, the seal comprising a main seal body having a central axis of rotation, the main seal body including an inner wall and an outer wall and opposing first and second sides, a raised rib extending out from the first side, the raised rib being axially deformable in such a manner as to create an axial force parallel to the axis of rotation for reducing the axial slip between a constant velocity joint a transmission output component, a flange seal portion extending out away from the outer wall, the flange seal portion having an inner contacting surface for contacting the constant velocity joint and defining a protective seal between the constant velocity joint and the transmission output component and a rigid coupling member connected to the main seal body having an inner wall portion for contacting the transmission output component whereby the rigid coupling member supports the main seal body and connects the seal to the transmission output component.
