Abstract
Abstract The present invention is a gasket assembly for sealing a gap between adjacent surfaces of mating components. The gasket assembly includes a core member having at least one opening extending therethrough. The gasket assembly also includes at least one seal member disposed in and circumscribing the opening. The gasket assembly further includes a plurality of tab members extending alternatingly into the opening for supporting the seal member between the tab members and within the opening.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
144 words
A gasket for sealing a gap between adjacent surfaces of mating components, comprising: a core member having a first and second outer surface and means forming at least one opening extending therethrough; at least one seal member disposed in and circumscribing said at least one opening; and means extending alternatingly into said at least one opening for supporting said seal member; wherein said supporting means comprises a plurality of tab members disposed circumferentially about said at least one opening and extending coplanar from said first and second outer surface, respectively, alternatingly into said at least one opening such that either one of said tab members of said first and second outer surface is disposed between a spaced pair of said tab members from the other said outer surface for supporting said seal member between said tab members and within said at least one opening.
Claim 2
Dependent Claim
