  • Patent number: 11248704
    Abstract: A metal gasket exhibiting an excellent seal effect on external foreign matter, such as salt water, and having low reaction force when required sealing pressure is low. The metal gasket, which is sandwiched between a pair of housings to seal the internal space of the housings and prevent entrance of external foreign matter between the housing and the gasket, has a straight portion, where the entire surface from an inner peripheral edge portion to an outer peripheral edge portion is a planar shape. A bent bead portion, directed obliquely outward and contacting one of the housings, is integrally provided in the outer peripheral edge portion of the straight portion. The bent bead portion functions as both an inward seal sealing the internal space and an outward seal preventing the entrance of external foreign matter between the housing and the gasket.

  • Patent number: 7475882
    Abstract: An air intake manifold gasket has a perforated core of metal including protrusions or tangs extending from a first planar surface and a second planar surface of the core. Joined to each planar surface of the core is an expanded graphite sheet to form a gasket body having planar surfaces. Screen printed to form a bead on peripheral edges of the planar surfaces of the gasket body is a silicone foam rubber material adapted to replace traditional silicone rubber structures used for the same purpose. The silicone foam rubber material includes a foaming agent that causes the material to expand during an oven-curing period. The amount of expansion of the silicone rubber coating is up to three times the thickness of the coating originally applied. As disclosed, the oven cure is for approximately 10 minutes at about 300 degrees Fahrenheit.

  • Patent number: 7407164
    Abstract: In order to produce a gasket that is adapted to be arranged between two components requiring sealing of which at least one contains a first metallic material which is less noble than aluminium and the gasket comprises at least one gasket layer including a plate consisting of a second metallic material which is nobler than the first metallic material, such that contact corrosion on the components requiring sealing is reduced or completely prevented, it is proposed that the gasket layer should comprise a sealing element which is arranged at an outer boundary region of the plate, should consist of an elastomer material and, in the installed state of the gasket, should gasket the gap between the gasket layer and the component which contains the first metallic material in a substantially fluid-tight manner.

  • Patent number: 7306235
    Abstract: A manifold gasket includes a carrier frame with a plurality of media-conveying openings corresponding to openings communicating between two parts to be clamped, such as an intake manifold and a cylinder head. Elastomeric sealing material is molded to the carrier frame about the openings to seal the openings when clamped. A compression limiting device is disposed on the carrier frame and is isolated from direct contact with the carrier frame by intervening elastomeric bonding material to limit compression of said elastomeric sealing material when the gasket is clamped between the head and block. The elastomeric bonding material renders the compression limiting device free-floating relative to the carrier frame.

  • Patent number: 7278639
    Abstract: An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.
