ABSTRACT:
A compound seal for affecting a seal on a translating shaft movable within a sleeve to separate high pressure and low pressure zones. The compound seal includes a sealing member and a clamping member disposed in a groove formed in one of the elements. The sealing member defines sealing sides which cooperate with one of the sides of the grooves and with the other of the elements. The clamping member cooperates with the bottom and the high pressure side of the groove, and with the sealing member so as to exert a force thereon extending substantially along the bisector of an angle defined by the sealing sides.
