High pressure device and method for clean room applications |
摘要 |
The invention relates to a device creating a hydraulic power stroke for closing a container by means of a rotationally symmetrical lifting system in a very compact form, said device containing a displaceable working piston and a displaceable booster piston which are respectively guided in cylinders. The working piston is hydraulically driven and the booster piston is pneumatically driven, both pistons being in direct axial active communication by means of a fluid located in a cavity between the bottom surface of the working cylinder and the front side of the booster piston. The front side of the working piston at least partially forms the closure of the container or is rigidly connected to the closing element of the container.
