Abstract

A metallic cylinder head gasket for an internal combustion engine having cylinder liners, the gasket comprising at least one cover plate which has a plurality of openings, commensurate with the combustion chambers of an internal combustion engine. The gasket has beads which extend around the openings, the beads being arranged at a distance from the edges of the openings. An annular upward extension is arranged concentrically with respect to each bead and serves as an upward extension of the combustion space and as a deformation limiter for the bead. The gasket is provided with at least one flat carrier plate. The upward extensions are formed by rings which are supported by the liner collars.
