ABSTRACT:
A composite seal for use between a movable element and a static element in a fluid pressure system where pressures vary on opposite sides of the seal. The seal comprises a fluoronated hydrocarbon sealing ring with a finely grooved sealing surface and an elastomer loading ring. The loading ring is a static seal and normally imposes radial force on the dynamic sealing ring and under increased fluid pressure deforms the peripheral grooves, forcing entrained fluid from them. The sealing ring has recovery characteristics which tend to restore the deformed grooves without readmitting fluid into the grooves, establishing a pressure differential which adheres the sealing ring to the surface to be sealed.
