摘要： A valve, connectable to a source of compressed gas, having a closing member movable into and out of a valve closing position, and a triggering mechanism by which the closing member can be moved from that position. Gas pressure in the valve holds the closing member in its valve closing position until the triggering mechanism is actuated. The triggering mechanism includes a cam segment and a cam follower pin, the pin being positioned to unseat the closing member when induced to do so by movement of the cam segment. The valve can be used to control the flow of propulsion gas through a spear-fishing gun. A spear is mounted on a rod through which compressed air is forced. The compressed air is forced out through openings in the side of the rod so as to act on a flexible sleeve which in turn acts against the open end of the spear mounted on the sleeve. The pressure on the open end of the spear holds the spear in place while sufficient pressure for projecting the spear is being built-up in the hollow portion of the spear. The closed end portion of the hollow area of the spear is adjacent the open end of the rod from which the compressed air flows.
