Abstract

A control apparatus for supplying at least one hydraulic consumer with fluid has a variable displacement pump (10) controlled by a load-sensing pressure (LS). For a case-by-case increase in the volume flow in the supply of fluid (22) to the hydraulic consumer, the load-sensing pressure (LS) is passed via a control line (28) to a control circuit (2) that 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 circuit (2).
