Abstract:
1. A gasket comprising a first metallic layer portion comprised of steel and having a bead formed therein, wherein said bead circumvents a port; and a second metallic layer portion comprised of steel and including at least one region of undulating profiling extending at least part of the way around said port to form at least a portion of a deformation limiter for the bead, the undulating profiling and the bead being radially spaced, wherein said undulating profiling is defined, at least in part, by a material thickness between a first undulating surface and a second, generally opposing, undulating surface, the first undulating surface defining a wave crest generally radially aligned with a wave trough defined by the second undulating surface, the first undulating surface defining a wave trough generally radially aligned with a wave crest defined by the second undulating surface, and the first and second undulating surfaces defining a transition region extending between the wave crest and the wave trough, wherein said material thickness of said undulating profiling is generally not constant such that the material thickness defines a taper formed within the transition region to a material thickness that is less than the material thickness of at least a portion of each of the wave crest and the wave trough, and wherein the wave crest and the wave trough are both generally sinusoidal.
