  • Patent number: 9664285
    Abstract: A flat seal having at least one single-piece sheet-metal seal layer is provided, which has at least one first layer region provided with at least one medium through opening and, outside the first layer region, at least one second layer region and, with the flat seal installation-ready, has a pre-determined outer contour, wherein the flat seal for the medium through opening has a medium-sealing device. In order to reduce the material requirement for manufacturing the seal layer, the seal layer is configured so that at least one sub-region of the second layer lying outside the medium-sealing device region of the seal layer is formed by a region of the sheet-metal layer that is stretched in the layer plane to achieve the pre-determined outer contour.

  • Publication number: 20160040783
    Abstract: Metallic flat gasket for installation between sealing surfaces, which face each other, of components conducting hot gas, which are connected to one another, the metallic flat gasket including a gasket plate which is compressed when the gasket is installed and which has at least two metallic gasket layers arranged one above the other and several hot gas through-openings, the gasket plate having between at least two adjacent hot gas through-openings a gasket plate web which separates the hot gas through-openings from one another. The gasket is configured such that the sum of the material thicknesses of the gasket layers in the region of a gasket plate web is less than in other gasket plate regions bordering on the hot gas through-openings, although the gasket also has in the region of this web at least one gasket layer.

  • Patent number: 8328203
    Abstract: A sealing system, in particular for sealing multiple part exhaust-gas lines for an internal combustion engine, has at least a first flange part (9) and a second flange part (11) guiding a flow of heat (5). The flange parts (9, 11) delimit a receiving space (33) for at least one sealing element (31) between them and adjoin one another. Each flange part forms an outwardly projecting annular flange (13) facing away from the flow of heat (5), and extending transversely with respect to the heat flow. Chambering of the receiving space (33) is formed for the sealing element (31) by an annular groove (45) open at the end face (17) of at least one flange part (11) and recessed axially into said end face (17). At least one covering element (47) is arranged in the annular groove (45) and provides thermal shielding for the sealing element (31) at least on its side facing the end face (17) of the flange part (11).

  • Patent number: 6974137
    Abstract: Flat gasket with a gasket plate comprising at least one sheet metal layer, in which fluid passage openings, screw holes adjacent to these and elastically deformable sealing elements enclosing the fluid passage openings are formed. On the one hand, to impede as little as possible sliding movements of the components to be arranged on either side of the flat gasket relative to one another and to the flat gasket, and, on the other hand, to create a fixed point for the assembled flat gasket, the flat gasket is designed such that the gasket plate has for at least a first one of its fluid passage openings in the area of a screw hole adjacent to this opening a spring element which is capable of elastic deformation perpendicularly to the gasket plate, and that the gasket plate has for at least a second one of its fluid passage openings adjacent thereto a screw hole which is without a spring element.

  • Patent number: 6371490
    Abstract: Flat gasket with a gasket plate which has at least one screw hole for the passage of the threaded shaft of a screw and is formed in the region of this screw hole by a sheet-metal layer, the sheet-metal thickness of which would make an engagement of the sheet-metal layer in a thread of the threaded shaft possible, wherein for the secure centering of the threaded shaft in the screw hole the sheet-metal layer has in its edge region bordering on the screw hole at least one centering element which is formed by the sheet-metal layer and bent out of its plane and prevents any engagement of the sheet-metal layer in a thread, the centering element being designed such that it can be bent back at least approximately into the plane of the sheet-metal layer during the tightening of the screw.
