Claims (1)
ポートと制御圧ポートとの開度が変化され、該制
御圧ポートに信号圧に応じた制御圧が発生される
減圧弁において、 上記元圧ポートと上記制御圧ポートとの所定開
度以上で連通し、上記信号圧の一部をドレンする
ドレン流路を設けたことを特徴とする減圧弁。[Claim for Utility Model Registration] The opening degree of the source pressure port and the control pressure port is changed through a movable element that is moved in accordance with the signal pressure, and a control pressure is generated in the control pressure port in accordance with the signal pressure. A pressure reducing valve characterized in that a drain passage is provided which communicates with the source pressure port and the control pressure port at a predetermined opening degree or more and drains a part of the signal pressure.
