Latest Patents
Harman holds a patent for a "Spring-energized cylinder head combustion seal assembly." This invention features a spring-energized cylinder head combustion seal designed to be positioned in an inwardly opening annular groove in a cylinder liner. The seal effectively prevents the leakage of combustion gases, ensuring optimal performance. The assembly includes a C-shaped annular sheath that contacts the bottom surface of the annular groove and the lower surface of the cylinder head. A helically wound spring, shaped as an annular ring, is housed within the C-shaped sheath. This design allows the seal assembly to be directly exposed to combustion gases and elevated temperatures, enhancing its effectiveness. The materials used for the spring and sheath are superalloys, with the exterior of the sheath potentially plated with soft metal to improve the metal-to-metal seal between the liner and cylinder head.
