Abstract (en)
[origin: WO2018210550A1] The invention relates to a control apparatus for supplying at least one hydraulic consumer with fluid having a variable displacement pump (10) which may be controlled by means of a loadsensing pressure (LS), characterized in that, for a case-by-case increase in the volume flow in the supply (22) to the hydraulic consumer, the loadsensing pressure (LS) is passed via a control line (28) to a control device (2) which ensures the increase in the supply (22) by connecting in a constant-displacement pump (16) as soon as an operator calls for the relevant function by operating the control device (2).
