Claim 7:
8. The dilute phase powder pump according to claim 1,
wherein a pump housing is provided in which the powder-conveying injector is at least partially accommodated, wherein a powder supply channel is formed in the pump housing which fluidly connects the powder inlet of the dilute phase powder pump to the powder inlet of the drive nozzle, wherein the valve device is designed to disconnect a fluidic connection formed by the powder supply channel between the powder inlet of the dilute phase powder pump and the powder inlet of the drive nozzle; and
