ABSTRACT:
A metallic cylinder head gasket for an internal combustion engine comprises a carrier plate sandwiched between flat cover plates, the multi-layer structure having a pattern of openings as dictated by the arrangement of engine cylinders, head mounting bolts and fluid flow passages. Resilient beads which cooperate with the carrier plate to form ring seals are formed in the cover plates and are arranged coaxially with respect to the apertures in the gasket. The beads are offset radially outwardly from the edges of the apertures and a deformation limiter is provided between each bead and the edge of the coaxial aperture, the deformation limiters being in the form of either a pair of oppositely directed, generally trapezoidal shaped deformable beads in the support plate or a single such trapezoidal shaped bead and a cooperating ring member which covers the concave side of the bead.
