| 摘要 |
The present invention relates to a device for a hydraulic system, which system comprises a number of hydraulic cylinders (20, 11) and a number of accumulators (27, 40), pre-charged at a certain pressure, which communicate via connections (25, 42) with one side of the hydraulic cylinders, in which the force in one movement direction of the cylinder is obtained mainly from the energy stored in the accumulator. The invention is characterized in that a hydraulic line (26, 84) is connected to said connection between accumulator and hydraulic cylinder, capable of supplying hydraulic oil at a pressure which is equal to or somewhat below the selected pre-charging pressure in the accumulator. |
