Flat Gasket

Abstract

A flat gasket, as used for example as a cylinder head gasket in internal combustion engines may have a first layer and at least one through-opening which extends through all the layers of the flat gasket. The first layer may have a filling channel which extends in the layer plane to the through-opening in the first layer. A circumferential edge of the through-opening in the first layer may have a moulded-on seal which contains or is made of an elastomer and which runs around the through-opening and extends into the filling channel. In the uncompressed state of the flat gasket, the elastomeric filling of the filling channel may have in a region of the filling channel adjacent to the circumferential edge of the through-opening in the first layer, a region that is thickened perpendicular to the layer plane of the first layer.
