ABSTRACT:
Cylinder head gasket with a ring-shaped metallic sealing element extending around a through-opening of the gasket, wherein, for automatic adaptation to changes in the width of the sealing gap to be sealed by the cylinder head gasket, the sealing element is of such spherical shape in cross section at its sides facing the two main surfaces of the gasket as to result in convex surfaces of the sealing element that face the main surfaces of the gasket and each have a crest, and, in the unpressed state of the gasket, these crests, in cross section perpendicular to the longitudinal center axis of a metallic sealing strand forming the sealing element, are laterally offset from one another in the direction of a gasket plane defined by the gasket so that the spacing of planes running parallel to the gasket plane and tangentially to the convex surfaces of the sealing element varies when these convex surfaces tilt about the longitudinal center axis of the sealing strand.
