Hydraulic system and a working machine comprising such a hydraulic system
A hydraulic system for a working machine includes at least one work function and a control valve unit for controlling hydraulic fluid to and from the work function, and a recovery unit connected to a return port of the control valve unit for recovering energy from the work function. The system further includes an arrangement for limiting the pressure of the hydraulic fluid at the return port, which pressure limiting arrangement has a pilot-operated valve adapted to set a maximum allowable pressure at the return port of the control valve unit. The pressure is variable by controlling the pilot-operated valve by a control unit.
