摘要：A method is provided for recovering energy in a hydraulic system of a workingmachine. The hydraulic system includes at least one hydraulic cylinder for movement of a
load, and a fan driven by a hydraulic motor. The file method includes pressurizing thehydraulic cylinder with a load pressure at one of the piston side and the piston rod sideof the hydraulic cylinder for moving the load, the load pressure substantially exceeding apressure difference between the piston side and the piston rod side of the hydrauliccylinder required to move the load, creating a counter pressure at the other of thepiston side and piston rod side of the hydraulic cylinder, where the counter pressure iscreated by means of the hydraulic motor while the hydraulic motor is driven by ahydraulic return flow from the hydraulic cylinder, by creating the counter pressure bymeans of the hydraulic motor while the hydraulic motor is driven by a return flow ofhydraulic fluid from the hydraulic cylinder, the counter pressure created by the hydraulicmotor being a function of the magnitude of the return flow driving the hydraulic motorand the load on the hydraulic motor. Energy consumption of a vehicle can be reduced in asimple and cost-effective way.
