Cylinder head steel sealing gasket - is contained in annular grooves in head and cylinder liner interface, and has convex contact contours

摘要

The gasket (3) is intended as a cylinder head (7) seal of an internal combustion engine. It consists of a ring which is contained with clearance in an annular groove (2) in the cylinder liner (1) on cne side and a corresponding annular groove (8) in the bottom face of the cylinder head on the other one. The ring is made of steel and has its upper and lower surfaces (4,5) convexly contoured. The radius of the curvature of this contour is between six and thirty times the width of the ring. The maximum height (v) of the ring is preferably greater than the sum of the depths of the two grooves.
