The invention relates to apparatus for supplying a pressurized fluid to a hydraulic system. The apparatus has a diverting path in parallel with the main supply line which is designed and is operable to minimize the inherent losses associated with such a diverting path. In the unit herein the diverting path has a pressure regulating valve and constant pressure drop valve in series. A control line branches from between the two valves and a load sensing is utlized to bias the pressure regulating valve in a closing direction. |
