CYLINDER HEAD GASKET

摘要

The cylinder head gasket includes a gasket layer which presents an inner periphery that surrounds an opening. The gasket layer has a first thickness adjacent the inner periphery. A combustion seal is positioned in the opening and extends circumferentially around an axis. The combustion seal is joined with the inner periphery of the gasket layer. The combustion seal has a height that is greater than the first thickness of the gasket layer. The combustion seal includes at least one seal body which is generally C-shaped as viewed in cross-section and is resiliently flexible for maintaining fluid tight seals with the cylinder head and the engine block. The C-shaped seal body presents a pocket which faces away from the inner periphery of the of the gasket layer for receiving combustion gasses during use to improve the fluid tight seals established with the cylinder head and the engine block.

主权项

1. A method of making a cylinder head gasket assembly for establishing a fluid tight seal between art engine block and a cylinder head, comprising the steps of:
preparing a gasket layer including at least one inner periphery which surrounds an opening; bending a length of a strip of metal into a C-shape with a pocket as viewed in cross-section; bending the C-shaped strip of metal around an axis into a ring and with the pocket facing radially inwardly towards the axis; joining opposite ends of the C-shaped ring together; and joining an outer diameter of the C-shaped ring with the inner periphery of the gasket layer.
