Abstract:
1. A device for creating and conveying a gas-powder mixture at an increased pressure, comprising: a powder container comprising a powder holding chamber structured and arranged for holding a powder and a vacuum line opening into a region of the powder holding chamber; a mixing chamber structured and arranged for mixing gas and powder; a gas supply line structured and arranged to supply gas at an increased pressure into the mixing chamber; at least one powder supply duct arranged between the powder holding chamber and the mixing chamber to carry the powder from the powder holding chamber into the mixing chamber; and a mixture outlet line structured and arranged for removing a gas-powder mixture from the mixing chamber, wherein the vacuum line is directly connected to the gas supply line so that the gas flowing in the gas supply line generates a reduced pressure within the powder holding chamber relative to a pressure in the mixing chamber to generate within the powder supply duct a gas flow directed counter to a powder flow direction.
