Abstract
Flat gasket, in particular, cylinder head gasket with a gasket plate which has at least one aperture and at least one sheet-metal layer which is provided with a bead surrounding the aperture, as well as with a stopper device preventing any excessive bead deformation; so that the sheet-metal layer does not tear even during dynamic pressure loads on the bead in the bead area which accompany a considerable flattening of the bead, the recess formed by the bead is filled over at least a considerable part of its depth with an elastomeric material which has appreciable flow properties under pressure even at ambient temperature (21° C.), i.e. is plastically deformable to a not inconsiderable extent.
