制御圧油供給管内に圧油が充填後に圧油阻止弁を
全開操作することを特徴とする圧油装置。 In a pressure oil system, there is a pressure oil prevention valve in the middle of the control pressure oil supply pipe from the pressure oil tank to reduce the frequency of operation of the pressure oil pump due to oil leakage from the hydraulic equipment when the hydraulic equipment is stopped. By structuring the check valve with a small opening function, when the pressure oil check valve is opened, it is temporarily in the small open position, and the pressure oil is blocked after the pressure oil is filled in the control pressure oil supply pipe on the secondary side of the pressure oil check valve. A pressure oil device characterized by fully opening the valve.
