Abstract: A solenoid actuated valve (10) holds pressure and volume of an accumulator with low leakage and provides low actuation drag during a release stroke for dumping fluid contents of the accumulator at very low current draw. Two elongate valve members (10a, 10b) are assembled to be movable axially relative to one another with a gland or groove (10c) formed in one of the two valve members (10a). An o-ring (12) located within the groove (10c) is in a non-contacting relationship to the other valve member (10b) when in a non-energized state. An energizer ring (14) located within the groove (10c) can reciprocate axially with respect to the o-ring (12). The energizer ring (14) moves axially toward the o-ring (12) in response to fluid pressure against a surface (14a) of the energizer ring (14) opposite from the o-ring (12) to axially compresses the o-ring (12), causing the o-ring (12) to expand radially outwardly into sealing contact with the other valve member (10b).
