  • Spray coating device for spraying coating material, in particular coating powder
    Patent number: 7478763
    Abstract: A spray apparatus for coating material, in particular for coating powders, contains a spray outlet spraying the coating material, a shaping air outlet in the form of a plurality of holes shaping the spray jet and an ambient-air passage radially configured between the spray outlet and the holes to aspirate ambient air by means of the flow suction effect of the spray jet and/or of the shaping air flow.
    Type: Grant

  • Powder spray coating device
    Patent number: 6951309
    Abstract: A powder spraycoating apparatus includes at least one compressed-air outlet (8) connected to a source (14) of compressed air from which it receives compressed air (15) at such a rate and such pressure that the compressed air at the compressed-air outlet (8) shall detach the powder's rim layer from the powder duct (4) and shall concentrate the powder flow toward the radial flow center and make it swirl, at a site near the downstream end (6) of the powder duct (4).

  • Powder spraycoating apparatus
    Publication number: 20030042341
    Abstract: A powder spraycoating apparatus comprising at least one compressed-air outlet (8) connected to a source (14) of compressed air from which it receives compressed air (15) at such a rate and such pressure that the compressed air at the compressed-air outlet (8) shall detach the powder's boundary layer from the powder duct (4) and shall concentrate the powder flow toward the radial flow center and make it swirl, at a site near the downstream end (6) of the powder duct (4).
