【実用新案登録請求の範囲】[Scope of utility model registration request] コントロールバルフヲ制御スルリモコン弁ノ一次側管路
に設けられたリリーフ弁の出口側管路と、リモコン弁の
二次側管路から分岐させた管路− との間に、制御弁が
設けられ、その制御弁は、リモコン弁の不使用時にリリ
ーフ弁の出口側管路からリモコン弁の二次側管路への油
の流入を許容し、その逆流を阻止するように構成されて
いることを特徴とするリモコン弁のヒート回路。A control valve is provided between the outlet side conduit of the relief valve provided in the primary side conduit of the remote control valve and the conduit branched from the secondary side conduit of the remote control valve. , the control valve is configured to allow oil to flow from the outlet side conduit of the relief valve to the secondary side conduit of the remote control valve when the remote control valve is not in use, and to prevent oil from flowing back. Features a remote control valve heat circuit.
