ABSTRACT:
A bidirectional pressure supply system for consumers of pneumatic negative pressure and/or positive pressure has a negative pressure line system and a positive pressure line system, to which the respective pressure types are simultaneously admitted from a pressure generator. Upon the electrically triggerable operation of the generator the consumers are connected, via parallel connected directional valves assigned to the consumers, to the respective pressure line system depending on the pressure type required at that moment, individually or in groups. The system provides an arrangement to apply negative pressure to first consumers and, simultaneously, positive pressure to second consumers.
