ABSTRACT:
The invention relates to the application of a projection to a metal layer of a metallic cylinder-head gasket for an internal-combustion engine having at least one elastic metal sheet, which is provided with one opening or a plurality of adjacent openings depending on the number of combustion chambers of the internal-combustion engine, a bead being provided in the at least one elastic metal sheet around each opening, at a distance from the latter, so that a straight section of sheet metal is left clear in the region of the edge of the opening, for which bead a spring travel limiter or stopper, which runs coaxially with respect to the bead and is formed by the projection, is provided, the projection being produced from a mixture which contains a plastic with a high mineral filler content. A mixture of an elastomer in particular with a filler which has been surface-treated by means of a silane is used.
