Abstract
The nozzle is provided with a plurality of cooling channels running from an annular channel located in an inlet region of the nozzle through the nozzle in longitudinal direction up to an outlet region of the nozzle. The powder supply channels provided for the supply of coating material are led between the cooling channels. A nozzle support member adapted for receiving the nozzle is provided with cooling ducts that are hydraulically connected to the cooling channels of the nozzle and constitute therewith a nozzle cooling circulation system. The advantages of this design can be seen in the facts that the nozzle is homogeneously and efficiently cooled up to its outlet end and that the danger of building-up molten deposits within the nozzle is substantially avoided.
