A potable hydraulic supply device is provided to supply the fluid at the fixed pressure and to easily operate a cylinder. A potable hydraulic supply device comprises a case(10), a hydraulic pump(30), a pressure control valve(34), a directional control valve(40), a supply line(44) and a return line. The case can open and close the inside storage space in covers(12,12a). The hydraulic pump is located inside the case and generates the hydraulic pressure by inhaling the fluid through an inhaling line extending to the outside. The pressure control valve controls the pressure of the fluid with cyclic supply or the hydraulic pressure supplied from the hydraulic pump. The directional control valve converts the fluid flowing direction with being connected to the pressure control valve. The supply line and the return line connect an operation unit and the directional control valve in order to operate operation unit of the outside. |
