A HYDRAULIC SYSTEM

摘要

The present invention relates to a hydraulic system (100) adapted to operate an extrusion press (22) by changing the pressure of the system (100), and consequently the press force of the extrusion press (22) between a minimum value, and a maximum value. The hydraulic system (100) comprises an accumulator system (102) comprising both liquid and compressed air, wherein the compressed air is arranged In between the liquid in the accumulator system (102).
