<p>An actuator lock is provided to prevent movement of an actuator until the actuator lock is released. A first member (4) of the lock is movable in response to fluid pressure within a chamber (23, 62) to move from a locked position to an unlocked position allowing the actuator to move. The first member is held at the unlock position by a latching member (30, 66) so that the lock cannot return to the locked position. During testing of the actuator, a test member (20, 56, 80) is operable to reversibly move the first member from the locked position to an unlocked and unlatched position. <IMAGE></p> |
