Abstract
Fluid actuator includes a lock mechanism for releasably locking the actuator against movement, and a lock release assembly including a lock piston engageable with a toggle linkage upon application of fluid pressure to the lock piston to release the lock mechanism. The toggle linkage is fixedly mounted on a rotatable cross shaft which may also be manually rotated by manual rotation of an external lock release lever attached to one end of the cross shaft for effecting manual release of the lock mechanism. The engaged or disengaged condition of the lock mechanism may be sensed electrically as by providing a target on the external lock release lever for movement therewith toward and away from a proximity switch.
