路。 In a hydraulic circuit configured such that a hydraulic pilot valve and a hydraulic pilot switching valve are connected by a pilot pipe, and the hydraulic pilot switching valve is switched by controlling the hydraulic flow by the hydraulic pilot valve, the pilot pipe and the tank are connected. An internal pilot switching valve is provided between the tank and the tank, and the internal pilot switching valve is switched between a neutral position communicating the pilot line with the tank and an internal pressure generated by flow resistance to connect the pilot line from the tank. A hydraulic circuit characterized by comprising a switching position for shutting off.
