ABSTRACT:
A device for power actuating a valve or other controlled unit, including a member operable by movement in opposite directions to move the controlled unit to different positions, a spring yieldingly urging the member in one of those directions, and a latching mechanism which is urged by the pressure of a body of fluid to a condition releasably retaining the member against movement by the spring. The latching mechanism is constructed to have a mechanical advantage enabling a relatively small force exerted by the body of fluid to resist a much greater force exerted by the spring. The latching mechanism includes two latching elements which are interengageable to releasably retain the member against movement by the spring, with one of the elements being shiftable in opposite directions by a manual operating member to manually actuate the member and also to vary the position in which the latching mechanism retains the member.
