ABSTRACT:
A fluid actuator includes a lock mechanism for releasably locking the actuator against movement, and a lock release lever engageable by a lock piston upon application of system pressure thereto to release the lock mechanism. The lock mechanism includes an axially movable lock member for respectively engaging and disengaging the lock mechanism depending on its position. Attached to the movable lock member is a proximity sensor target which moves with the axially movable lock member toward and away from a proximity switch to provide an electrical signal indicating the locked or unlocked condition of the lock mechanism in accordance with the proximity of the target to the switch. A cover may also be provided for respectively concealing or exposing the target depending on the position of the axially movable member to provide a visual indication of the unlocked or locked condition of the lock mechanism.
