A gasket is disclosed that includes an edge structure and a honeycomb structure surrounded by the edge structure.

The seal has a support body at which at least one sealing body is provided. The support body is electrically conductive at least in a region projecting past the at least one sealing body. The at least one sealing body seals against a penetrating medium while the support body shields against emission of electrical disturbance sources.

An engine includes an engine block and a cylinder head mounted to the engine block. The engine block includes a bore elongated along an axis and a liner disposed in the bore and extending annularly about the axis. The liner includes a seal surface and a fire dam disposed radially inward from the seal surface. The fire dam extends along the axis from the seal surface towards the cylinder head. The engine further includes a head gasket disposed between the engine block and the cylinder head. The head gasket extends endlessly around the fire dam. The engine further includes a shim seated between the seal surface and the head gasket and abutting the seal surface and the head gasket. The shim is disposed radially outward from the fire dam and extending annularly about the axis.

A layered head gasket includes a gasket core, a head-layer, a block-layer, and a plurality of apertures. The head gasket may be useful for sealing an internal combustion engine having a cylinder head, a cylinder block, a plurality of combustion chamber passageways, a plurality of coolant passageways, and a plurality of oil passageways. The gasket core is made of a copper sheet. The head-layer may be made of spring steel and may be fixed to a top side of the gasket core, being configured to interface with the cylinder head. Likewise, the block-layer may be made of spring steel and may be fixed to a bottom side of the gasket core, being configured to interface with the cylinder block. The plurality of apertures may pass through the head-layer, the gasket core, and the block-layer.

A bead gasket for sealing off an axial joint between a first component and a second component, the bead gasket including a first bead loop surrounds a first inner region in an axial view and includes a bead end face for an axial contact with one of the components; a passage for fluid which is located in the first inner region, wherein the first bead loop is a smallest bead loop surrounding the passage; and a first rigidifying structure which extends from the first bead loop into the first inner region in the axial view in order to rigidify the first bead loop.

A multi-layered metal sheet is disclosed formed of a laminate of a plurality of metal sheets fixed to each other by a clinch formed in a concave shape from one main surface toward another main surface, the clinch has an schematic pillar shape, the clinch being defined by an open top, a pair of cut surfaces which are respectively formed from the open top toward a bottom, a pair of inclined surfaces respectively inclined from the open top toward the bottom, transitional surfaces which connect the cut surfaces and the inclined surfaces to each other, and the bottom having overlapping parts which extend over the main surface of the multi-layered metal sheet on a lower side immediately below the cut surfaces, and lengthwise end portions of a cut formed in each of upper edge portions of the cut surfaces are disposed on upper edge portions of the transitional surfaces.

A gasket assembly includes a gasket body, an adhesive-backed film, and a plurality of grommets. The gasket body includes a first face, and the adhesive-backed film includes a sticky face bonded to the first face of the gasket body. The grommets are bonded to the sticky face of the adhesive-backed film.

Provided is a gasket formed by coating rubber on both surfaces of a metal plate. In order to suppress stress relaxation, the gasket is provided with: a base formed by a flat plate-like metal member; and a seal portion including as a base body a seal base that is formed to a thickness smaller than that of the base and formed by a flat plate-like metal member having a rubber-like elastic material layer on a surface thereof. The seal portion is provided with a bead formed in a bent shape. The base and the seal portion are formed in, for example, annular shapes having different diameters. The base and the seal portion are coupled to each other by a coupling portion in such a way that the base and the seal base are positioned in the same plane and that the bead protrudes from a plane including at least one surface of the base.

A gasket is disclosed that includes an edge structure and a honeycomb structure surrounded by the edge structure.

A positioning arrangement for positioning a sheet metal element on a flange joint includes a flange with a medium passage opening, and a mating flange with a medium passage opening. The mating flange is connected to the flange with a plurality of fastening screws and the respective medium passage openings of the flange and the mating flange communicate with each other. The positioning arrangement also includes a sheet metal element with an abutment section. The abutment section is arranged in an abutment plane between the flange and the mating flange around the medium passage openings. The sheet metal element also includes at least three first tabs, which are arranged at a first through-hole of the sheet metal element and project transversely to the abutment plane into a first receiving hole in the mating flange. The at least three first tabs are received with radial clearance in the first receiving hole. The sheet metal element is positioned relative to the flange via the first tabs
