Abstract

A hydraulically actuated mechanical lock assembly, including a lock actuator comprising a lock housing and a moveable element mounted in the lock housing, wherein the housing is arranged to receive hydraulic fluid at a first end (Chamber A) from a source of high pressure fluid via a return line, and at a second end (Chamber B) from a source of high pressure fluid via a control line, whereby the relative pressures in Chambers A and B are controlled, via the control line, to cause movement of the moveable element between a locked position and an unlocked position; and a lock valve arranged between the return line and the control line to control the flow of hydraulic fluid into Chambers A and B; wherein the return line is configured to be connected between the source of high pressure fluid and the lock valve via chamber A of the lock actuator.
