間に通じる導入通路の間にパイロツト弁を配置し
、一面に圧力設定ばねの弾性力を他面に二次側圧
力を作用させたダイヤフラムの撓みでパイロツト
弁を駆動し、パイロツト弁の開閉によりピストン
上面に作用する流体圧力を制御して、ピストンに
連結した主弁を開閉するようにしたパイロツト式
減圧弁に於いて、ピストンの中心軸を中心とした
円周上にそれぞれ等間隔に複数の導入通路を形成
した、パイロツト式減圧弁。 A pilot valve is arranged between the primary side passage leading to the primary side and the introduction passage leading to the space above the piston, and the pilot valve is operated by the deflection of the diaphragm, which has the elastic force of a pressure setting spring applied to one side and the secondary side pressure applied to the other side. In a pilot type pressure reducing valve, the main valve connected to the piston opens and closes by driving the valve and controlling the fluid pressure acting on the top surface of the piston by opening and closing the pilot valve. A pilot type pressure reducing valve with multiple introduction passages formed at equal intervals around the circumference.
