Claims (1)
弁を直列に隣接させて装入し、ポペットをスプリングに
よりスライド弁に向けて付勢してポペットの針弁をスラ
イド弁に設けた貫通孔の周縁を弁座として当接せしめ、
スライド弁とスプール弁を中間に挿入したスプリングに
より反対方向に付勢してスライド弁をタンクポートに通
ずる油路に設けた環状の弁座に当接せしめ、スプール弁
とスライド方間の油室をポンプポートに連通させるとと
もに、スライド弁とポペット間の油室をドレンポートに
連通させたことを特徴とする圧力制御弁。A poppet, a slide valve, and a spool valve are inserted in series and adjacent to each other in the inner cavity of the valve body, and the poppet is biased toward the slide valve by a spring, so that the needle valve of the poppet is attached to the periphery of the through hole provided in the slide valve. is brought into contact with it as a valve seat,
A spring inserted between the slide valve and the spool valve is biased in opposite directions to bring the slide valve into contact with an annular valve seat provided in the oil passage leading to the tank port, thereby opening the oil chamber between the spool valve and the slide. A pressure control valve characterized by communicating with a pump port and communicating an oil chamber between a slide valve and a poppet with a drain port.
