A hydraulic system for supplying a hydraulic fluid to a hydraulically-operated component. A pump for delivering component the hydraulic fluid from a reservoir is connected with the reservoir through a flow control valve. The control valve is a 4/3 directional flow control valve, in which two valve outlet connections are connected to a suction side of the pump and two valve inlet connections are connected to the reservoir. A flow restriction is positioned in each of the conduits extending from the reservoir to the valve inlet connections for reducing the energy consumption of the pump when the need for hydraulic fluid is low. |
