Hydraulic system i.e. dispenser-slave-force deflection system, for e.g. deep drawing press, has piston, where counter pressure on piston is generated with compressible container i.e. hydraulic cylinder, that is located within piston

摘要

The hydraulic system has a slidable piston (9) supported in an accumulator (6) in a liquid-proof manner. The piston is pressurized by a hydraulic fluid, where a corresponding counter pressure is exerted on the piston. The counter pressure on the piston is generated with a compressible container i.e. hydraulic cylinder, on a side that is turned away from the hydraulic fluid. The container encloses a predetermined gas amount, where the container is located within the piston.
