ABSTRACT:
A seal assembly 18 for blocking the leakage of fluid between a first region 26 and a second region 28 is disclosed. Various construction details are developed for improving the sealing capability under operative conditions which cause a severe reverse pressure gradient across the seal assembly. In one particular embodiment, the seal assembly includes a seal 36 having a front 88 which faces the first region and a pair of sidewalls 92, 94 which extend from the front and are urged apart by a spring means 96.
