  • Patent number: 6824453
    Abstract: There is described a surface treatment nozzle which generates a surface treatment jet that comprises a suspension of surface treatment material and gas and a surrounding liquid-containing jet for preventing dusting. The surface treatment jet has a high velocity compared with the velocity of solely liquid and is conveyed in an inner tube (13; 31) and the liquid is conveyed in a channel (12) between the inner tube and a tube (11) concentrically surrounding the inner tube. There is included a mixing arrangement (14, 15, 16; 22; 29, 30, 25) for mixing the liquid with gas upstream of the nozzle outlet and to impart to the liquid/gas mixture a velocity in the same order of magnitude as the velocity of the surface treatment jet at said outlet.
