Tooling synchroniser piston-controlled chambers

摘要

A working chamber (31) has as many control chambers (32,33) as cylinders served (7,8). Each control chamber has its own outlet (51,52) and contains an equal volume and the pistons (61,62) in the respective control chambers are rigidly joined into a unit (6). The chambers stand concentrically in the housing (1) as do their respective pistons, the housing in the form of a tee whose beam holds the working chamber (31) and pistons (61,52) as opposed to the beam web which houses the control chambers. Each chamber base (321, 331) outlet runs parallel to the adjoining control chamber(s) and issues in the housing base, using oil as medium or gaseous fluid, and with each chamber joined to a pressure accumulator.
