Abstract

The invention relates to a metallic cylinder head gasket for an internal combustion engine, having a carrier plate which is arranged between cover plates. The carrier plate and cover plates are provided with passages which are commensurate with the combustion chambers of the internal combustion engine. The cover plates are provided, around each passage, with a resilient bead. Adjacent to each bead, and also extending around each passage, is a bead deformation limiter. The deformation limiters are shaped to prevent the occurrence of high edge pressures.
