Multi de-energizing cylinder for use as hydraulic cylinder for quick interruption of flow of power in e.g. presses, has pistons successively arranged in series under summation of piston concentrated loads in another de-energizing cylinder

摘要

The cylinder has multiple pistons successively arranged in series under summation of piston concentrated loads in another multi de-energizing cylinder. Individual portions are integrated in a thin gradated cylinder tube (3), where outlets (18) of the gradated cylinder tube are integrated at outlets (26) in a desk (4) or a plunger of a press. Inner covering plates are pushed away from the individual portions in the outlets lying inside the gradated cylinder tube. The individual portions are supported by conical maximum-force retention rings (9) or a maximum-force lock (11). Independent claims are also included for the following: (1) a positive quick lock mechanism for supporting round components (2) a maximum-force retention ring for supporting round components.
