Metallic flat gasket

摘要

The invention relates to a metallic flat gasket with at least one metallic gasket layer, which is mainly flat and shows a first and second surface, wherein a plane of the gasket runs centered between said flat areas, wherein a camber is formed within the gasket layer, which protrudes over the first surface of the gasket layer and which has a larger length than width, wherein the camber possesses a first level given by a virtual level, which runs in parallel to the plane of the gasket through the foot of the camber on the first surface of the gasket layer and a second level, given by a further virtual, which runs through the highest point of the camber and also parallel to the plane of the gasket of the gasket layer, wherein the camber possesses a slope area that ascends between the two levels. The slope area is provided with an undulating structure such that it comprises at least two waves each with a wave crest and a wave trough.

1. A metallic flat gasket with at least one metallic gasket layer, which is mainly flat and shows a first and second surface, wherein a plane of the gasket runs centered between said flat areas, wherein a camber is formed within the gasket layer, which protrudes over the first surface of the gasket layer and which has a larger length than width, wherein the camber possesses a first level given by a virtual level, which runs in parallel to the plane of the gasket through a foot of the camber on the first surface of the gasket layer and a second level, given by a further virtual level, which runs through the highest point of the camber and also parallel to the plane of the gasket of the gasket layer, wherein the camber possesses a slope area that ascends between the two levels, comprising:
the slope area is provided with an undulating structure such that it comprises at least two waves in the direction between the two levels each with a wave crest and a wave trough;wherein in the area of the undulating structure the thickness of the gasket layer in the area of the flanks between the wave crests and wave troughs is reduced by 5 to 40%, relative to the thickness of the gasket layer in the area of the wave crests or wave troughs.
