Abstract: A control device for controlling a hydraulic consumer (2), such as a working cylinder, has at least one control valve (18) having a control spool (20). Control spool (20) is guided in a valve housing (22) in a longitudinally movable manner and is actuated by an electric motor (24). Electric motor (24) can be controlled by control electronics (MC), which receive input signals from a sensor device (58, 60, 62) detecting at least one operating state of the consumer (2).

Abstract: A mobile working machine, in particular an agricultural device such as a self-propelled sprayer, comprising a structure which is hydraulically supported with respect to an undercarriage by means of cylinders (2, 4) having a piston chamber (6) and a rod chamber (8), wherein a switching device (18, 22, 36, 38) is provided which, in a switching position, fluidically connects the piston chamber (6) of a cylinder (2, 4) to the rod chamber (8) of another cylinder (2, 4), and vice versa, characterised in that, as part of the switching device, first valves (18, 22) and second valves (36, 38) are connected on the fluid-conveying connection (12, 14) between the piston chamber (6) of the one cylinder (2, 4) and the rod chamber (8) of the other cylinder (2, 4), the first valves (18, 22) each being connected on the input side to the piston chamber (6) and to a first hydraulic accumulator (28, 30) and the second valves (36, 38) being connected on the input side to the rod chamber (8) and on the output side to a second hydr

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).
