Abstract

The invention relates to a device for creating and conveying a gas-powder mixture having a powder receiving space (3) that is connected to a vacuum creation device via a vacuum line (19) that discharges to the upper region of said powder receiving space. A reduced pressure in comparison to a mixing chamber (7) can be created within the powder receiving space (3), and thus a gas flow directed against the powder flow direction within a powder supply channel (6).
