The present invention addresses the problem of enabling an amount of compression of a bead part to be ensured and sealing properties to be improved in a gasket that is supported on one side with a bolt hole provided only on one side of the bead part. A gasket (1) is provided that has an opening (103) to be sealed, a bead part (12) provided along a circumference of the opening (103), and a bolt hole arranged on one side of the bead part (12). The gasket (1) is arranged between a case (101) and a cover (102) and is fastened with a bolt to seal the opening (103) while being supported on one side by the bolt (200). A height adjusting part (14) is provided in a side edge portion (1a) that is located on the opposite side of the bolt hole from the bead part (12). The height adjusting part (14) regulates a gap between the case (101) and the cover (102) during fastening with the bolt and serves as a fulcrum to press the cover (102) into contact with the bead part (12).

A gasket is provided to reduce a reaction force in an attached state and suppress deterioration of sealing performance due to a corrosive foreign matter such as salty water and a snow melting agent. A gasket includes a metal base plate made of metal, and a covering layer formed of an elastic body that covers at least a part of the metal base plate. The metal base plate includes a pair of an upper face and a lower face that are back-to-back to each other, a bead portion protruding toward a side facing the upper face, an inner periphery portion extending from an inner periphery edge of the bead portion, and an outer periphery portion extending from an outer periphery edge of the bead portion. The outer periphery portion extends toward a side facing the lower face, in an oblique manner with respect to a protruding direction of the bead portion.

A coating solution comprising an organic solvent solution containing polyol-crosslinkable fluororubber, a polyol vulcanizing agent, and N-phenyl-3-aminopropyltrialkoxysilane, preferably a coating solution further containing an epoxy resin in addition thereto, and a fluororubber metal laminated sheet formed by applying the above coating solution to a metal sheet, followed by vulcanization. The coating solution can not only impart stability over time to the fluororubber paste, but also improve the interlayer adhesion and abrasion resistance of the fluororubber metal laminated sheet. Therefore, when it is used as a cylinder head gasket, it is possible to cope with the reduction in rigidity due to the increase in combustion pressure of the engine, and with weight saving. As a result, it will greatly contribute to the improvement of fuel efficiency of automobiles.

An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

A gasket for a combustion chamber is provided. The gasket comprises a plated surface extending across at least a portion of the metal base. In the gasket, at least a portion of the plated surface includes a laser treated section with a first raised surface that protrudes away from the metal base and the laser treated section is arranged in a mid-span that is arranged between two cylinder openings.

Seal ring groups to be assembled with edges of through holes of a gasket includes a plurality of sealing groups. One of the plurality of sealing groups has an inner peripheral shape different from an inner peripheral shape of another of the plurality of sealing groups to distinguish one sealing group from another sealing group.

A gasket manufacturing method, which enables an improvement in sealing performance by making the thickness of a gasket formed on a bead on a base member more uniform. The manufacturing method of a separator-integrated gasket includes dispensing a gasket material, and curing the gasket material dispensed on the bead. The bead includes portions having different widths in a short direction thereof. Compared to a moving speed of a dispensing apparatus relative to the separator body in a narrow portion where the width is small, the moving speed is slower in a wide portion having a larger width than the narrow portion.

In accordance with at least one aspect of this disclosure, a fuel seal for an aircraft fuel system includes a seal ring of a metallic material configured to retain a shape of the seal ring under compression, and a coating of elastomeric material, over molded onto the seal ring and configured to conform to a shape of a sealing surface. In embodiments, the seal ring and coating can be configured to provide drop-tight sealing at a temperature of at least 400 degrees F. In certain embodiments, the seal ring and coating can be configured to seal one or more fuel system components of an aircraft fuel system.

A multi-layer head gasket having at least two active layers and a shim layer sandwiched there between. The gasket and shim layer include cylinder openings aligned with the cylinders disposed within an engine block. The shim layer incorporates a plated portion for adding topography to an otherwise flat shim layer, the areas of plating determined based on FEA and/or pressure film load testing, for improving fatigue resistance, sealing pressure, and/or loading characteristics of the gasket.

A rubber-metal laminate that includes a metal member; and a rubber layer provided on the metal member, wherein the rubber layer has a 100%-modulus value in accordance with JIS K6251 of 8.5 MPa or more and a thickness of 80 μm or more. A gasket that includes the rubber-metal laminate.
