を特徴とするハツチカバー開閉装置の油圧回路。 In the hydraulic circuit of the hatch cover opening/closing device, which is equipped with a hydraulic cylinder that pushes the hatch cover from the seating position onto a predetermined running path and a hydraulic motor that rotates in both opening and closing directions and moves the hatch cover on the running track, pressure oil is supplied to the hydraulic motor in the opening direction. The oil passage A for supplying pressurized oil in the closing direction and the oil passage B for supplying pressurized oil in the closing direction are selectively connected to the pump and tank via a switching valve, while the oil passage C with a check valve interposed therebetween is connected from the oil passage A to the oil passage B for supplying pressurized oil in the closing direction. The oil passage C is branched and connected to the extension side of the hydraulic cylinder.
A hydraulic circuit for a hatch cover opening/closing device, characterized in that the switching valve is provided with an independent section that branches a return passage from between the check valve and the hydraulic cylinder and connects the return passage to a tank.
