Patent ID: 7000924

Claim:
A gasket comprising: a metallic layer having a bead formed therein, wherein said bead circumvents a port; at least one metallic layer having an upper surface and a lower surface, wherein said at least one metallic layer includes at least one region of undulating profiling around said port radially adjacent to said bead to form a deformation limiter for said bead, wherein said deformation limiter elastically maintains at least a portion of said undulating profiling when the gasket is installed, said region of undulating profiling including a crest, a trough and at least one transition between said crest and said trough and wherein said crest is a portion of one of said surfaces, said trough is a portion of the other of said surfaces, and said transition extends therebetween a shape of said bead being distinct from said undulating profiling; and wherein said at least one metallic layer further comprises a spring steel or a cold deformable steel that hardens during tempering, and wherein said deformation limiter is not folded over, a shape of said bead being distinct from said undulating profiling.
