Abstract
A seal assembly includes an annular body coupled with an inner member or an outer member and has inner and outer circumferential surfaces and first and second annular sealing portions spaced along a centerline. The two sealing portions either extend radially outwardly from the outer surface and have an outside diameter, with the first portion diameter being greater than the second portion diameter, or extend radially inwardly from the body inner surface and have an inside diameter, with the first portion diameter being lesser than the second portion diameter. The seal body is radially deflectable such that the first sealing portion is engaged with one of the outer and inner members, and the second sealing portion is spaced from the member, when the body is exposed to pressure lesser than a predetermined value and both sealing portions are engaged with the member at pressures above the value.
