  • Publication number: 20090224486
    Abstract: Cylinder head gasket having a single-layered or multilayered metallic gasket plate with sealing beads in at least one metal layer, which are elastically deformable in height and surround the combustion chamber through-openings, and deformation delimiting devices which delimit the flattening of the sealing beads; in order to achieve as good a sealing function as possible in the long term and as good a protection as possible of the sealing beads against inadmissibly high deformations during operation of the engine, deformation delimiting devices, one of which is formed by a meandering bead stamped into a metal layer, and the other by a plurality of elevations stamped out of a metal layer, are provided radially inside and radially outside the sealing beads.

  • Publication number: 20070157999
    Abstract: Flat gasket with a gasket plate which has at least one sheet metal layer which consists of a spring steel sheet, has elastic properties and is provided with at least one bead, which can be deformed elastically in its height and is subject to a dynamic pressure load under conditions of use of the flat gasket, and in order to achieve a greater operative range of the bead without reducing its durability consists of an austenitic steel according to the European standard EN 10088-2-1.4372.
