Claims (1)
ポートとドレンポートとの中間に形成された出力
油圧ポートと、スプールを一方向に押すべく信号
油圧が入力される信号油圧室と、信号油圧と対向
する方向へスプールを押すべく出力油圧が帰還さ
れる出力油圧帰還室とを有し、出力油圧ポートが
入力油圧ポートまたはドレンポートと選択的に連
通する調圧弁において、上記信号油圧室を信号油
圧の脈動に伴つて容積変化可能としたことを特徴
とする調圧弁。 An input hydraulic port, a drain port, an output hydraulic port formed between the input hydraulic port and the drain port, a signal hydraulic chamber into which a signal hydraulic pressure is input to push the spool in one direction, and a signal hydraulic chamber facing the signal hydraulic pressure. The pressure regulating valve has an output hydraulic pressure return chamber to which the output hydraulic pressure is returned to push the spool in the direction, and the output hydraulic pressure port selectively communicates with the input hydraulic pressure port or the drain port. 1. A pressure regulating valve characterized by being able to change its volume according to the change in volume.
