Claims (1)
圧力を開方向に作用し、流入路から絞りを有して
パイロツトリリーフ弁に接続するパイロツト通路
を設けパイロツト通路の絞り後の圧力を主弁体に
閉方向に作用させ、パイロツト通路へ絞りの後に
他の絞りを設け、他の絞り前後の圧力差が所定値
を越えると開いてパイロツト通路の両絞り間より
低圧部へ分流させる圧力感応形制御弁を設けたパ
イロツト操作形圧力制御弁。 The pressure of the inflow passage acts in the opening direction on the main valve body that opens and closes between the inflow passage and the outflow passage, and a pilot passage connected from the inflow passage to a pilot relief valve with a restriction is provided to reduce the pressure after the restriction of the pilot passage. Pressure that acts on the main valve body in the closing direction, provides another throttle after the throttle in the pilot passage, opens when the pressure difference before and after the other throttle exceeds a predetermined value, and diverts the flow from between the two throttles in the pilot passage to the lower pressure part. Pilot operated pressure control valve equipped with a sensitive control valve.
