減圧して前記出力ポートに供給する減圧型パイロ
ツト弁において、前記スプールと前記プツシヤと
の間に、プツシヤの押圧により前記バネを介して
スプールが設定された適宜の減圧位置まで摺動し
たときから減圧量を小さく変化させるバネを設け
たことを特徴とする減圧型パイロツト弁。 A casing having a pump port, a tank port, and an output port, a spool provided within the casing for switching the output port to the pump port or the tank port, and a pusher connected to the spool via a spring, In the pressure reducing pilot valve, the pressure oil from the pump port is reduced in pressure and supplied to the output port by pressing the pusher and sliding the spool via a spring, in which the pressure oil is reduced between the spool and the pusher. A pressure reducing type pilot valve characterized in that a spring is provided which changes the amount of pressure reduction to a small value from when the spool slides to a set appropriate pressure reduction position via the spring due to the pressure of the pusher.
