Abstract (en)
The generator has venturi nozzle with a flow cross section that deviates from a circularity. Two plates are arranged in parallel relationship and joined in sandwich construction, with one of the plates constructed to accommodate the venturi nozzle. A pressure sensor or flow sensor is fluidly connected to the flow cross section for process supervision. A flap valve is in parallel relation to a plane of the venturi nozzle for closing a suction cross section. The venturi nozzles are constructed so as to be individually controlled for connection or disconnection.
