Patent ID: 8496253

Claim:
A metallic flat gasket, comprising: at least one gasket layer having two surfaces and having at least one combustion chamber through-opening which is surrounded by an elastically deformable sealing element which is configured in the form of an undulatory profiling in the gasket layer in such a way that on each of said two surfaces of the gasket layer at least two wave crests and two wave troughs are present, annularly surrounding the combustion chamber through-opening, an unloaded state thickness of the gasket layer in the region of the sealing element being greater than the original thickness of the gasket layer, wherein, apart from the undulatory profiling, no further sealing or support elements circumscribe the combustion chamber through-opening in said gasket and wherein the sealing element has, when subjected to linear compression of from 500 to 2,800 N/mm in a direction which is substantially perpendicular to a plane of the gasket layer, a linear compression thickness which is from 0.05 to 0.3 mm greater than the original thickness of the gasket layer, the gasket layer having at least 4 through-openings for fastening means and also at least one further through-opening for lubricant or coolant that is surrounded by an elastomer sealing element, and the combustion chamber through-opening having a diameter of less than 200 mm.
