The intermediate plate is divided into two pieces, steps are formed by the two pieces, and spaced formed between the pieces are provided with thermal spray stoppers.
Claims5
A metallic gasket having bores therein corresponding to combustion chambers and comprising a pair of spaced elastic metallic base plates, said base plates having inwardly extending projections defining beads around said bores, an intermediate plate disposed between said base plates and including two pieces laminated together at said beads, said pieces having edge surfaces disposed adjacent said bores and including outwardly extending steps between said beads and said edge surfaces to define spaces formed between said pieces and opening at said edge surfaces, and a thermal spray stopper disposed within each of said spaces.
