ABSTRACT:
A gasket assembly for interposition between a pair of axially spaced-apart interface surfaces of an internal combustion engine. The assembly includes a metal retainer member having generally planar first and second surfaces with one or more apertures formed therethrough. Each of the apertures are configured for generally coaxially registration with a corresponding fluid passageway formed through the interface surfaces of the engine as having a periphery defining a margin of an extent greater than the inner diameter of the corresponding fluid passageway. One or more generally annular seal members are each received within a corresponding one of the apertures as including a first and second radial surfaces. The radial surfaces, which define a bearing portion between interface surfaces of the engine, extend inwardly of the corresponding aperture from an outer diametric extent to an inner diametric extent which defines an opening of the assembly configured for generally coaxial registration with a corresponding one of the fluid passageways of the engine. Each of the seal members is formed of a layer of a lamellar graphite sheet material which is compressible axially in the bearing portion of the seal member between the interface surfaces for sealing about the corresponding fluid passageway of the engine.
