Device for supplying several pneumatic transport systems with transport gas under pressure has blow-off line with blow-off control element, excessive flow and pressure maintenance control unit

摘要

The device has a central supply gas line into which several parallel, selectively operable pressure generators (3a-3c) open, from which parallel selectively operable transport lines (6a-6c) emanate, each of which contains a transport system (2a-2c) and to which is connected a blow-off line (7) with a blow-off control element and an excessive flow and pressure maintenance control unit (10). The excessive flow and pressure maintenance control unit is a pneumatic device.
