Abstract

Cylinder head gasket is provided having a single-layered or multilayered metallic gasket plate with sealing beads in at least one metal layer, which are elastically deformable in height and surround the combustion chamber through-openings, and deformation delimiting devices which delimit the flattening of the sealing beads. In order to achieve as good a sealing function as possible in the long term and as good a protection as possible of the sealing beads against inadmissibly high deformations during operation of the engine, the deformation delimiting devices, one of which is formed by a meandering bead stamped into a metal layer, and the other by a plurality of elevations stamped out of a metal layer, are provided radially inside and radially outside of the sealing beads.
