ABSTRACT:
A seal assembly for a downhole hydraulically operated oil well pump has a dovetail shaped groove around the exterior of the pump body and a seal element mounted therein. The seal element has an inner side resting against the groove bottom, one end of a full thickness filling that end of the groove and extending therefrom toward the opposite end having a recess portion around the outer perimeter thereof forming a lip about a mid-portion of the seal element which is deformed by fluid pressure acting toward that end of the seal to urge the lip outward into sealing contact with a pump housing which encloses the pump body.
