吐出口と油圧機器との連通流路を形成するコネク
タ内にオリフイスを設け、このオリフイス前後の
油圧圧力差に応じて作動され、この作動量に応じ
た油量を上記連通流路からオイルポンプの吸込口
へ還流させるスプールバルブを上記コネクタに対
向させて具備する流量制御弁において、このスプ
ールバルブ先端に形成した筒状部を上記コネクタ
開口部に貫入してオリフイスを構成するとともに
、このスプールバルブ内に該オリフイス下流側と
スプールバルブ他端側弁孔内とを連通する連通孔
を穿設したことを特徴とする流量制御弁。 An orifice is provided in a connector that faces the oil pump's discharge port and forms a communication flow path between this discharge port and hydraulic equipment. In the flow control valve, the flow control valve is provided with a spool valve facing the connector, which returns the amount of oil from the communication channel to the suction port of the oil pump, and a cylindrical part formed at the tip of the spool valve is inserted into the connector opening. What is claimed is: 1. A flow control valve comprising an orifice, and a communication hole formed in the spool valve for communicating between the downstream side of the orifice and the inside of the valve hole at the other end of the spool valve.
