An engine shutdown valve comprises a substantially circular gate valve (25) movable about an axis between open and closed positions within a valve housing (16) mounted in an engine induction manifold. A gate lever (23) connects the gate valve (25) with the axis and a movement mechanism (43, 52) acts to move the lever between the two positions. A restraining mechanism (36, 37) holds the gate lever (23) and the gate valve (25) in the open position and a release mechanism (49, 55, 57) is operable to release the restraining mechanism (36, 37) when desired. The restraining, release and movement mechanisms are all located in a latch housing (17) which is located exteriorly of the valve housing (16) and the manifold. |
