Cylinder-head gasket and manufacturing method
Abstract
Abstract The invention describes a flat gasket, in particular a cylinder head gasket, which consists of a pressure-resistant, non-deformable material. In contast to known flat gaskets, it is permanently deformed even before installation. During this procedure, the sealing face is deformed outwards in a shape complementary to the bending of the faces to be sealed, with the result that the thickness distribution required for the necessary pressure distribution is present at all points exercising a load-bearing function during use. The corresponding topography is obtained by clamping a deformable built-in master under operating conditions between the faces to be sealed and making copies of this built-in master. <IMAGE>
