  • Fastening means in sealed gasket assembly including shoulder bolt
    Patent number: 4456268
    Abstract: A means maintaining compressive force in a seal assembly to assure seal reliability. The valve cover is fastened to the engine head with a shoulder bolt which carries Belleville washers compressively positioned between the bolt head and valve cover. The gasket load and deflection is determined by the compressive force or gasket loading of the Belleville washers on the unthreaded length of the shoulder bolt. The resilience of the Belleville washers maintains a continuous force on the gasket for the life of the sealed assembly.
