Abstract
A sealing element for sealing flange faces on internal combustion engines, comprising at least one annular metal profiled body, characterized in that the profiled body is made of a wire and comprises at least one core region and at least one bending region, the material thickness of the wire is designed to be greater in the core region than in the respective bending region, and the wire in the core region is provided with at least one connecting means for direct or indirect connection to at least one further component. A radial cross-section of the sealing element is banana-shaped with a center region of the banana-shape being the sealing element core region and an end region of the banana-shape being the bending regions.
Claims30
A sealing element for sealing flange faces on internal combustion engines, comprising at least one annular metal profiled body, made of a wire, radial cross-section of the wire comprising at least one core region and two bending regions, the thickness of the sealing element in an axial direction of the sealing element in the core region being greater than in the bending regions, and in the core region at least one connecting means for direct or indirect connection to at least one further component, and the radial cross-section of the sealing element being in the shape of a longitudinal, axial cross-section of a banana, a center region of the banana-shape forming such core region and opposed end regions of the banana-shape forming the bending regions, and a height of the sealing element in an axial direction of the sealing element in the bending regions exceeding a height of the sealing element at the core region in an unstressed state of the sealing element.
