Device for controlling compensation chamber of e.g. bottle, molding unit, has pressurizing unit that is controlled for pressurizing of fluid i.e. hydraulic fluid, that is intended to be introduced selectively into compensation chamber

摘要

The device (10) has a pressurizing unit (20) that is controlled for pressurizing of a fluid e.g. hydraulic fluid or air, that is intended to be introduced selectively into a compensation chamber (14), where the hydraulic fluid consists entirely or partly of water or oil. The pressurizing unit is arranged with a hydraulic master cylinder that is arranged with a pressure chamber. A piston of the master cylinder is controlled in a selective manner by pneumatic actuation. The pressurizing unit is arranged with a pressure amplifier (200).
