Claims (1)
動する弁体駆動手段と、上記弁体に追従して伸縮
動作する可撓性隔膜と、この可撓性隔膜で仕切り
形成されて上記流体通路から一次圧力を導入し、
この一次圧力を上記弁体の開閉方向における一方
向押圧力として作用させ、この一方向押圧力を上
記弁体の反対側に作用する他方向押圧力と均衡さ
せるための圧力導入室とを備えた弁構造体。 A valve body that opens and closes the fluid passage, a valve body drive means that drives the valve body to open and close, a flexible diaphragm that expands and contracts in accordance with the valve body, and a partition formed by the flexible diaphragm to allow the fluid to flow through the fluid passageway. Introducing primary pressure from the passage,
A pressure introduction chamber is provided for causing this primary pressure to act as a one-way pressing force in the opening/closing direction of the valve body, and for balancing this one-way pressing force with another direction pressing force acting on the opposite side of the valve body. Valve structure.
