ABSTRACT:
In a cylinder head gasket with a gasket plate comprising at least three metallic plate layers superimposed one upon the other and at least one combustion chamber hole, with a beaded plate layer arranged on either side of an inner plate layer, each of the beaded plate layers having a bead enclosing the combustion chamber hole, protruding in the direction towards the inner plate layer and forming a combustion chamber sealing element, and with a metallic stopper ring immediately adjacent to the combustion chamber hole and enclosing this combustion chamber hole, the stopper ring being arranged radially inside the beads, bordering on an inner edge of the inner plate layer which encloses the combustion chamber hole, and projecting over the two main surfaces of the inner plate layer so as to delimit the deformability of the beads in the direction perpendicular to the plane of the gasket plate, in order to obtain a tension-free stopper ring and minimize the material waste, such a cylinder head gasket is constructed such that the stopper ring comprises a ring-shaped main body and at least one sheet metal ring, which are superimposed one on the other in the direction perpendicular to the plane of the gasket plate, the thickness of the main body of the stopper ring being a multiple of the thickness of the sheet metal ring, and the main body of the stopper ring being a part punched out of the inner plate layer.
