漸増室１４内の圧力にてポンプポート９とアクチェータ
ポートとの連通を閉じる方向に付勢されたスプール１１
を、調圧ばね１６を介して摺動子８にて押動することに
より開方向へ付勢するようにした切換制御弁において、
摺動子８に上・記スプール１１の閉Ｕ方向への付勢力に
対向する受圧面１８を有するブースタピストン１７を設
け、このブースタピストン１７が嵌合するブースタピス
トン室１９にアクチェータポートを連通したことを特徴
とする切換制御弁。The spool 11 is biased in the direction of closing the communication between the pump port 9 and the actuator port by the pressure in the pressure increasing chamber 14 into which the load spring 12 and the load piston 15 are fitted.
In the switching control valve which is biased in the opening direction by being pushed by the slider 8 via the pressure regulating spring 16,
A booster piston 17 having a pressure receiving surface 18 opposing the biasing force of the spool 11 in the closing direction U is provided on the slider 8, and an actuator port is communicated with a booster piston chamber 19 into which the booster piston 17 fits. A switching control valve characterized by:
