Abstract
A sealing assembly for sealing a clearance space between first and second members wherein the first member has a groove therein and the second member has a surface overlying the groove. The groove is defined by a base surface and two side surfaces. The first and second members are displaceable with respect to each other. The seal assembly includes a flexible generally annular sealing ring, generally T-shaped in cross section for being positioned within the groove. The ring has an axially extending leg intersecting a radially extending leg. The axially extending leg is for being positioned in engagement with the base surface of the groove. The radially extending leg includes converging side surfaces merging into converging end surfaces. The end surfaces are generally linear in cross section and merge into a generally arcuate transition surface when the ring is in an uncompressed state. The transition surface and at least a portion of the end surfaces are in facing engagement with the surface of the second member when the ring is in a compressed state. A complementary mating anti-extrusion ring is positioned within the groove juxtaposed to each side surface and the radially extending…
