Abstract: A combined intake-exhaust gasket for internal combustion engines comprising a gasket plate which has at least one metallic intermediate layer arranged between two outer metallic layers and in which at least one exhaust-outlet opening and one intake opening adjacent thereto are provided, each of which is limited by a sealing element. In order to seal the intake opening by means of an elastomeric sealing ring but also protect this ring from the high exhaust temperatures and mechanical wear and tear, the sealing element of the intake opening has a sealing ring which is made of elastomeric material and limits this opening as well as a web-like metallic support member which is secured to the sealing ring, projects outwardly therefrom in radial direction and is inserted loosely between the outer layers of the gasket plate.

Abstract: A reinforced support sheet or plate, especially for making flat gaskets or heat dampening plates is made of a sheet or plate-like support material which is covered with a vulcanizable soft material layer which contains a fiber-like and, if need be, powder-like binder material. The support material is smooth and the soft layer material is composed predominantly of a powder-like, asbestos-free mineral base material. The mineral base material may include mostly a chemically and thermally untreated material and also a chemically and thermally or only thermally treated material. A method for making such a sheet or plate is also disclosed.
