A static gasket and method of construction thereof is provided. The gasket includes a functional layer constructed of one type of metal having an opening bounded by an inner periphery an outer periphery. The gasket further includes a carrier layer constructed of a different metal than the functional layer. The carrier layer has an opening bounded by an inner periphery configured to receive the outer periphery of the functional layer in a line-to-line or loose fit. The functional layer is configured in substantially coplanar relation with the carrier layer with a first portion of the outer periphery of the functional layer being welded to a radially aligned first portion of the inner periphery of the carrier layer. A second portion of the outer periphery of the functional layer remains detached from a radially aligned second portion of the inner periphery of the carrier layer.

A sealing assembly for establishing a gas and fluid tight seal in an internal combustion engine is provided. The sealing assembly includes a plate of metal which has a plurality of openings and at least one generally flat surface. The plate also has at least one shelf which circumferentially surrounds one of the openings and which opens to the generally flat surface and the opening. The sealing assembly further includes at least one sealing bead of an elastically compressible material which is engaged with the shelf and extends outwardly therefrom past the generally flat surface for sealing the plate with another component in the internal combustion engine.

A metal gasket includes embossments that exhibit essentially full functional recovery and full retained internal stress at temperatures up to about 1000&#xb0; F. which is made from sheet material that is cold rolled and whose embossments are work hardened without any post embossment heat treating that would act to harden the material. This material may also receive a precipitation hardening heat treatment prior to being embossed. The gasket materials include alloys having greater than about 18% Ni, greater than about 14% Cr, from about 0.1 to 10% of at least one of Mo, Ti, V, Al, Co, Nb, Ta or Cu and the balance Fe with incidental impurities, which are cold rolled without any post embossment heat treating that would act to harden the material.

A spiral wound gasket () is disposed between joint members () of a hot fluid joint to seal a gap () therebetween. The spiral wound gasket () includes a first high temperature performance metallic strip () formed of a thermally conductive alloy, including, Ni Cr, and Fe, spirally wound around a central axis (A) to present a first high temperature performance metallic winding () exposed to hot fluids. A first non-metallic filler strip () formed of a mica material is spirally wound outwardly of the first high temperature performance metallic winding () to form a first non-metallic filler winding (). A second high temperature performance metallic strip () formed of a stainless steel material is spirally wound outwardly of the first non-metallic filler winding (). A second non-metallic filler strip () formed of a graphite material is spirally wound outwardly of the second high temperature performance metallic winding ().

Bi-metal spiral wound gasket

The invention provides a sheet metal joint and a method for forming a sheet metal joint. The sheet metal joint includes first and second metal sheets disposed in parallel relation to one another. Each of the first and second metal sheets has a plurality of perforations with a tang extending from each perforation. The tangs of the second sheet and the tangs of the second metal sheet are curled together in opposite rotational directions. The tangs of the first metal sheet space the first and second metal sheets from one another and the tangs of the second metal sheet substantially fixedly engage the first and second metal sheets with respect to one another.

A metal gasket formed from a suitable iron-nickel chromium alloy includes at least one embossment that exhibits essentially full functional recovery at temperatures exceeding 1000&#xb0; F. and including in the range of 1100&#xb0; F. to 1600&#xb0; F. or more and which is made from sheet material that is work hardened and strengthened by cold rolling, or a combination of cold rolling and precipitation hardening, without any post embossment heat treating that would act to further harden the material. Suitable iron-nickel-chromium alloys include those comprising, by weight, greater than 18% nickel; greater than 14% chrome and 0.1-10% of at least one element selected from the group consisting of Mo, Ti, V, Al, Co, Nb, Ta and Cu, with the balance being substantially Fe, wherein the gasket sheet alloy has a deformed microstructure.

Each of the first and second metal sheets has a plurality of perforations with a tang extending from each perforation. The tangs of the second sheet and the tangs of the second metal sheet are curled together in opposite rotational directions.

A metal gasket assembly has a gasket plate and an annular grommet. The gasket plate is formed with an opening having opposing surfaces adjacent the opening to define a predetermined fixed thickness of a plate. The annular grommet has an elastically deformable U-shaped body. The U-shaped body has legs presenting outer sealing surfaces defining an initial undeformed thickness that is greater than the thickness of the gasket plate. The opening formed in the gasket plate receives the grommet. A compressive force applied in a generally perpendicular direction to the opposing surfaces of the gasket plate deform the legs of the body to a reduced thickness corresponding substantially to the thickness of the gasket plate. When the compressive force is reduced with changes in operating conditions, the legs of the grommet return toward their original undeformed thickness to maintain a seal.

Metal plate gasket

A heat treat fixture is provided for supporting thin sheet-like work pieces, such as metal gasket layers, during heat treatment to achieve uniform hardness and properties of the work piece while preventing warpage. The fixture has porous, planar support walls that engage the opposite sides of the work piece. The walls include a coarse porous exoskeleton of expanded metal and an inner liner of wire mesh panels that are considerably finer than the coarse exoskeleton. The porous walls permit liquid heating and cooling media during heat treatment to flow freely through the walls for intimate contact with the work piece to achieve rapid uniform heating and cooling. The work piece is supported by the porous walls against movement out of its plane while being permitted to expand and contract within its plane to minimize warpage.
