摘要： A method for recovering energy in a hydraulic system of a working machine, the hydraulic system comprising at least one hydraulic cylinder for movement of a load, and a fan driven by a hydraulic motor, comprising the steps of pressurizing the hydraulic cylinder with a load pressure at one of the piston side and the piston rod side of the hydraulic cylinder for moving the load, the load pressure substantially exceeding a pressure difference between the piston side and the piston rod side of the hydraulic cylinder required to move the load, creating a counter pressure at the other of the piston side and piston rod side of the hydraulic cylinder, where the counter pressure is created by means of the hydraulic motor while the hydraulic motor is driven by a hydraulic return flow from the hydraulic cylinder, by creating the counter pressure by means of the hydraulic motor while the hydraulic motor is driven by a return flow of hydraulic fluid from the hydraulic cylinder, the counter pressure created by the hydraulic motor being a function of the magnitude of the return flow driving the hydraulic motor and the load on the hydraulic motor. The advantage of the invention is that the energy consumption of a vehicle can be reduced in a simple and cost-effective way.
