Abstract
A hydraulic system including a pump having a discharge line and a number of hydraulic energy consumers connected to the pump discharge line. A controller for the load-independent distribution of a pressure medium from the pump to the consumers includes a multiway valve located in the discharge line between the pump and each consumer to actuate the consumers. A pressure compensator for determining the flow of pressure medium to each multiway valve is located in the discharge line upstream of each multiway valve. Each pressure compensator is actuated as a function of a first pressure difference resulting from the pressure upstream of a multiway valve and the pressure downstream of the multiway valve and of a second pressure difference resulting from the discharge pressure from the pump and the highest load pressure of the consumers. At least one pressure difference of at least one pressure compensator is adjustable.
