ABSTRACT:
A free standing, continuous seal ring 54. The seal ring is effectively circumferentially continuous. The seal ring is adapted to extend between two circumferentially extending structures 38, 42. The structures 38, 42 separate a region 46 having a first pressure from a region 44 having a lower pressure. The seal ring is formed of two elements: a first element 78 having a circumferential gap G; and, a second element 80 extending across the gap G. Various construction details which enhance the efficiency of the seal ring are disclosed. In one particular embodiment, the second element is nested within the first element.
