Beschreibung
Zusammenfassung:	A dilute phase powder pump for pumping powder, particularly coating powder, from a powder reservoir to a powder spray-coating device, includes a powder inlet, which is or can be flow-connected to the powder reservoir, and a powder outlet, which is or can be flow-connected to the powder spray-coating device. The dilute phase powder pump also has a powder pumping injector with a motive fluid nozzle and a converging inlet nozzle, and has a valve device for optionally interrupting a flow connection between the powder inlet (80) of the dilute phase powder pump and a powder inlet of the motive fluid nozzle.
