It is a hydraulic source device consisting of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc., or a hydraulic device including a control valve. It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines in which the driving device is separated from the hydraulic station. By connecting the hydraulic station to the cylinder or motor with an oil pipe, the hydraulic system can achieve various specified actions.
