Patent number: 7980563Abstract: A flat gasket for sealing a seal gap between engine component sealing faces wherein the flat gasket comprises at least one first and second gasket layer adjacent to the first gasket layer, wherein at least one elastomeric sealing element is disposed at the first gasket layer and is formed from a sealing material which is applied to the first gasket layer and can be cured in situ, wherein at least one cut-out is provided at the second gasket layer, through which cut-out the elastomeric sealing element extends when the flat gasket is in the fitted pressed state, and wherein the flat gasket comprises at least one overflow space which receives excess, as yet uncured sealing material during assembly of the flat gasket and is disposed at least partly laterally next to the sealing element when the flat gasket is in the unfitted, unpressed state.Type: GrantFiled: February 5, 2007Date of Patent: July 19, 2011Assignee: ElringKlinger AGInventors: Oliver Hegmann, Thomas Stöckel, Matthias Baur

Patent number: 7059610Abstract: In order to produce a multi-layer gasket which comprises at least one first layer and one second layer and at least one connecting arrangement for connecting the layers of the gasket together wherein the layers of the gasket are connected together in a simple and reliable manner, it is proposed that the connecting arrangement should comprise at least one retaining element connected to the first layer and at least one through opening arranged in the second layer, wherein the retaining element and a retention area of the second layer partially overlap one another in an unconnected state of the layers, wherein, for the purposes of connecting the layers, the retaining element is deformable from the plane of the first layer and can be moved past the retention area, and wherein the retaining element grips behind the retention area of the second layer in a connected state of the layers in such a manner that the first layer and the second layer are safeguarded from a separating movement of the layers.Type: GrantFiled: April 21, 2003Date of Patent: June 13, 2006Assignee: ElringKlinger AGInventor: Oliver Hegmann

Patent number: 6631909Abstract: Flat gasket for sealing a sealing gap between sealing surfaces of machine components which are pressable against the flat gasket, the flat gasket having a gasket plate formed by several sheet metal layers and provided with at least one elastomeric sealing element in an area serving to seal a sealing gap area in which the component sealing surfaces lead to a locally varying sealing surface pressure at the flat gasket, the sealing element being arranged on a first one of the sheet metal layers and, in the mounted state of the flat gasket, extending through a cutout in a second sheet metal layer forming a first one of the main surfaces of the gasket plate; in order that the sealing element can already be applied by the gasket manufacturer, but, nevertheless, is protected against damage in the course of assembly of the machine components, the gasket is so designed that the sealing element is in the form of a sealing element formed from a material which is applied to the first sheet metal layer and is curable in sType: GrantFiled: May 17, 2001Date of Patent: October 14, 2003Assignee: Elringklinger AGInventor: Oliver Hegmann
