Abstract (en)

[origin: WO2012143614A1] The hydraulic system comprises a first subsystem (23) working within a first pressure range and a second subsystem (24) working within a second pressure range, where the upper limit is higher than the upper limit of the first pressure range. The system com- prises a pump (2) for supplying hydraulic fluid into the system and two pressure intensifiers (10, 10') for increasing the pressure in the second subsystem. The pressure intensifiers (10, 10') are piston-type pressure intensifiers with at least two alternative intensification ratios. The invention also concerns a method for operating a hydraulic system.
