Abstract

The invention relates to a hydraulic system for a work machine. The system comprising: a main hydraulic machine connected to an output shaft of an engine of the work machine for providing power to working hydraulics of the work machine; a main pressure line connecting the main hydraulic machine to the working hydraulics; a support hydraulic machine connected to the output shaft; a hydraulic accumulator; a discharge valve connected between the accumulator and an input side of the support hydraulic machine; a charge valve connected between an output side of the support hydraulic machine and the hydraulic accumulator to selectively allow a flow from the support hydraulic machine to the hydraulic accumulator; a flow support valve connected between the output side of the support hydraulic machine and the main pressure line to selectively allow a flow from the support hydraulic machine to the main pressure line; and a hydraulic tank connected to the input side of the support hydraulic machine.
