Gasket assembly and method of making same

摘要

A head gasket assembly for an internal combustion engine has combustion openings and a plurality of other apertures and comprises a pair of expansive gasketing layers (16) secured to each other. A sealing pattern (30) of elastomer or metal or the like is provided between the layers (16) so that they envelope the sealing pattern (30). The sealing pattern (30) surrounds the combustion opening and the apertures for enhancing the sealing effect of the gasket assembly in the zone of the sealing pattern, thereby to protect the sealing pattern from direct contact with the engine head and block. The sealing pattern (30) is adhered to one of the layers (16), and the layers are adhered to each other by adhesive under pressure in a zone closely surrounding the sealing pattern to restrict lateral movement of the sealing pattern (30) and to compress and densify at least one of the layers in the zones overlying the sealing pattern to enhance the sealing characteristics of the gasket assembly.
