<p>PROBLEM TO BE SOLVED: To distribute a volume flow rate from a pump regardless of load pressure without additionally disposing pressure compensators in adjustment valves of a plurality of consumption machines, when the consumption machines are simultaneously operated.SOLUTION: In a hydrostatic driving system, a pump 7 and consumption machines 2 and 3 are disposed, the consumption machines are respectively controllable by using adjustment valves 4 and 5 having throttling action, the adjustment valve is provided with a setting device 11 operable in relation to an electronic control signal and generating a setting signal, and an electronic control device 10 connected to the setting device, and a control signal to operate the adjustment valve is generated on the basis of the setting signal of the setting device. The setting signal of the setting device 11 forms a required volume flow rate of the consumption machine, and the electronic control device detects pressure drop in the adjustment valve, so that the electronic control device controls the adjustment valve in relation to the pressure drop detected in the adjustment valve and a through-flow characteristic line to the required volume flow rate of the consumption machine.</p> |
