<p>Actuator (1) includes a lock mechanism (20) for locking the actuator against movement in one end position, and a separate lock release assembly (35) exteriorly mounted on the side of the actuator housing (3). The lock release assembly includes a toggle linkage (41) directly engageable with the movable lock part (21) to disengage the lock (20) when a suitable force is applied to the toggle linkage exteriorly of the actuator. A lock spring (30) is located immediately between the movable lock part (21) and actuator piston (4) for resetting the lock as the actuator nears such one end position. </p> |
