Abstract

Bei einer Kaltgasspritzvorrichtung ist in einer Mischkammer (10) eine Strömungsleiteinrichtung (20) angeordnet, welche das Spritzpartikel/Gas-Gemisch von einem längsachsennahen Bereich nach außen in einen wandnahen Bereich der Mischkammer (10) drängt.

Figure imgaf001
In a cold gas spraying device, a flow-guiding device (20) is arranged in a mixing chamber (10), which urges the sprayed particle / gas mixture from a region close to the longitudinal axis to a region near the wall of the mixing chamber (10).
