弁４を弁座２に仲店して流路３を閉路守るとともに、前
記弁４の背面側に設けた弁杆５の延出部５ａに介設した
形状記憶合金製の第２スプリング７に通電して記憶形状
に変位させ、前記第１スプリング６の押圧力に抗して前
記弁杆５を引上げ弁４を弁座２から離脱して流路３を開
路する如く七た開閉弁。The pressing force of the first spring 6 acting on the back side of the valve 4 anchors the valve 4 to the valve seat 2 to keep the flow path 3 closed, and also prevents the extension of the valve rod 5 provided on the back side of the valve 4. A second spring 7 made of a shape memory alloy interposed in the protruding portion 5a is energized to be displaced into a memorized shape, and the valve rod 5 is pulled up against the pressing force of the first spring 6 to move the valve 4 to the valve seat 2. Seven opening/closing valves to open the flow path 3 by separating from the valve.
