Abstract
Cylinder head gasket whose gasket plate comprises a single sheet metal layer, combustion chamber openings, and for each combustion chamber opening a ring-shaped combustion chamber sealing element, which is a sheet metal ring that is arranged on the sheet metal layer and is joined to the latter by welding; to avoid the risk of damage to a combustion chamber sealing element as a result of sliding movements occurring between a cylinder head sealing surface and the cylinder head gasket while the engine is in operation, all sheet metal rings are arranged on that side of the sheet metal layer which is to face an engine block.
