Abstract
Nozzle system for a powder blasting device including a first nozzle element for transporting a powder-gas mixture stream along a transporting direction and a second nozzle element, where the second nozzle element surrounds the first nozzle element such that at least one channel is formed between the first nozzle element and the second nozzle element, where the channel is provided for transporting a liquid stream, where the first nozzle element and the second nozzle element are arranged such that in operation the powder-gas-mixture stream ejected by the first nozzle element is encased by the liquid stream ejected by the channel for forming an output stream of the nozzle system, where the first nozzle element has an acceleration part having a first cross section and a spreading part having a second cross section, where the spreading part is arranged downstream of the acceleration part.
