Abstract (en)
[origin: EP2644903A2] The method involves determining a pressure fluid volume supplied or discharged to a pressure chamber (6,8), to set a predetermined reference chamber pressure or a predetermined desired consumer location, such as a piston position of a hydraulic cylinder (2). The switching valve arrangement is controlled, such that the pressure chamber is removed or supplied with the predetermined hydraulic fluid volume. The actual pressure or the actual loading position are checked. The opening duration of the switching valve arrangement is modified to provide a desired hydraulic fluid volume. An independent claim is included for a digital hydraulic controlling arrangement for controlling of a consumer.
