Abstract:
In a metallic gasket adapted to be disposed between confronting surfaces of engine components with combustion bores to seal a joint between the confronting surfaces when clamping together the engine components opposed to each other;the improvement comprising a annular raised portion defining inside a gas hole in alignment with any combustion hole in the engine components, a surrounding metallic sheet arranged about the annular raised portion and connected to the annular raised portion, both the annular raised portion and the surrounding metallic sheet being made of aluminum material, and a soft sealing member deposited on the surrounding metallic sheet around the annular raised portion, wherein the annular raised portion and the soft sealing member come in abutment with any mating surface of the confronting surfaces when the gasket is squeezed in place between the confronting surfaces of the components, thereby sealing together the confronting surfaces, wherein the surrounding metallic sheet is recessed below any one surface thereof, where the soft sealing member is charged, and wherein the recess formed along the annular raised portion around any one of the adjacent gas holes merges with the recess formed along the annular raised portion around another of the adjacent gas holes at an area between the adjacent gas holes.
