作用せしめ、ダイヤフラムの下面には二次側圧力
を作用せしめ、両力の釣合によりパイロツト弁又
は直接主弁を開閉する減圧弁に、圧力設定ばねの
弾性力を調節する駆動手段として圧電素子を取り
付けたことを特徴とする自動設定減圧弁。 The elastic force of the pressure setting spring is applied to the upper surface of the diaphragm, and the secondary side pressure is applied to the lower surface of the diaphragm, and the pressure setting spring is applied to the pressure reducing valve that opens and closes the pilot valve or the main valve directly by balancing both forces. An automatic setting pressure reducing valve characterized in that a piezoelectric element is attached as a driving means for adjusting elastic force.
