Abstract:
Flat gasket for sealing a sealing gap between sealing surfaces of machine components, said sealing surfaces being pressable against said flat gasket, said flat gasket comprising a gasket plate formed by a sheet metal layer, said gasket plate being provided with at least one elastomeric sealing element in a gasket plate area serving to seal a sealing gap area in which the machine component sealing surfaces result in a locally varying sealing surface pressure at the flat gasket, said sealing element being arranged on a first main surface of the sheet metal layer, and a surface contour of the sheet metal layer defining at the second main surface of the sheet metal layer a plane of a maximum level of said surface contour parallel to the plane of the gasket plate in the unmounted, unpressed state of the flat gasket, wherein(a) the sealing element is in the form of an elongate strand-like sealing element formed from a material which is applied in the form of an elongate strand to the first main surface of the sheet metal layer and is curable in situ; (b) the sheet metal layer is provided in the area of the sealing element with a cutout for passage of the curable sealing element material therethrough, said cutout being shorter than the sealing element in a longitudinal direction of said sealing element; (c) the material of the sealing element is initially capable of undergoing plastic deformation at least at operating temperature of the machine components and the flat gasket such that in the mounted, pressed state of the flat gasket, the sealing element extends through the cutout of the sheet metal layer as far as the machine component sealing surface adjacent to the second main surface of the sheet metal layer; (d) the gasket plate and the sealing element are so designed that in the unmounted, unpressed state of the flat gasket, the sealing element extends at the most as far as said plane of the maximum level.
