Claims (1)
体的に突接した弁杆をボデイに形成した案内孔に
摺動自在に嵌入し、該弁杆を略直角に貫通するよ
うに形成した透孔に、通電により加熱されて収縮
する形状記憶合金製のワイヤを挿通し、該ワイヤ
の両端を前記弁体から離間する方向に屈曲させて
前記ボデイに固定した端子に接続したことを特徴
とする開閉弁。 A valve rod integrally abutted against a valve body biased in the valve closing direction by spring elasticity is slidably inserted into a guide hole formed in the body, and is formed to pass through the valve rod at a substantially right angle. A wire made of a shape memory alloy that shrinks when heated by electricity is inserted into the through hole, and both ends of the wire are bent in a direction away from the valve body and connected to a terminal fixed to the body. On-off valve.
