Abstract
A cylindrical seal ring 20 has an inwardly extending rib 60, and upwardly 66 and downwardly 82 extending cantilever arms, each carrying outwardly facing seal surfaces 68, 84. The cantilever arms preload the seals and support the seals while providing flexibility between the seal areas and the rib 60. Temperature transients are readily accommodated.
