摘要： A spring-energized cylinder head combustion seal for positioning in an inwardly opening annular groove in a cylinder liner for sealing the interface between the cylinder liner and cylinder head so as to prevent leakage of combustion gases includes a C-shaped annular sheath which is disposed in contact with the bottom surface of the annular groove and the lower surface of the cylinder head. The second component of the seal assembly is a helically wound spring which is of an annular ring shape and disposed within the C-shaped sheath. The sheath and spring are positioned such that the opening in the C-shaped sheath opens directly into the cylinder and the seal assembly is exposed directly to the combustion gases and the higher or elevated temperatures which are present. The spring and C-shaped sheath are constructed of superalloy materials and the exterior of the sheath may be plated with soft metal so as to provide an enhanced metal to metal seal between the liner and cylinder head.
