Abstract
A sealing ring assembly is disclosed for use in sealing the annular gap between two concentric cylindrical members, one of the members having an annular groove and the other member having a surface opposed to the groove. Deformable seal material and a radially expansible-contractible non-deformable split retaining ring are located in the groove, the seal material engaging one surface of the retaining ring and the retaining ring being positioned on one of the sidewalls of the groove. The seal material and the retaining ring extend radially to the surface of the other cylindrical member, the retaining ring being sized to elastically compress against that surface. The surface of the retaining ring facing the seal material is beveled or chamfered along a portion or all of its width, the beveled surface extending inwardly to the inner edge of the retaining ring. Fluid pressure applied to the seal material deforms the seal material and causes the seal material to urge the outer edge of the retaining ring against the surface of the other cylindrical member. The seal material is deformed to press against the surface of the other cylindrical member to provide a primary seal. The inner edge of the retaining ring is, preferably, spaced from the inner wall of the groove and under pressure the seal material deforms and flows into the gap formed between the inner edge of the retaining ring and the inner wall of the groove to prevent leakage of fluid around the retaining ring.
