<p>The invention relates to a fluid feed system for supplying a fluid consumption unit from at least two fluid pressure sources and comprising branch conduits for connection to said fluid pressure sources respectively and a main conduit to which said branch conduits are connected at their downstream ends the main conduit being connected to said fluid consumption unit. A flow regulating valve in each branch conduit, each flow regulating valve including a flow control element operable by a piston or the like to which can be applied a pressure variable to control the setting of the flow control element, and means for varying the pressures acting on the pistons or the like to maintain substantially equal flow rates in said branch conduits.</p> |
