Abstract: A hydraulic arrangement for supplying a consumer or actuator includes a first supply device that has at least one pump with an adjustable delivery volume. The hydraulic arrangement further includes a second supply device that is connected in parallel to the first supply device. The second supply device includes a loadable accumulator and a digitally regulated switching valve arrangement.

Abstract: The disclosure relates to a method for actuating a hydraulic valve arrangement, having a hydraulic continuously adjustable valve and having a hydraulic switching valve for providing a variable opening cross section, wherein an opening cross section threshold value is predefined, wherein, above the opening cross section threshold value, the switching valve is placed into a defined switching position and only the continuously adjustable valve is actuated, and wherein, below the opening cross section threshold value, the continuously adjustable valve is placed into a defined switching position and only the switching valve is actuated.

Abstract: A device for controlling a hydraulic actuator includes an electrically operated valve that controls the flow of a pressure medium in the actuator in response to the operations of three controllers. A first of the controllers designates a position of a piston of the valve. A second of the controllers commands movement of the actuator. And a third of the controllers electronically controls a sequence of movements of the actuator. The three actuators are arranged in a common housing located on the valve.
