CA 2166992

An advantageous improvement (10, 12) as to reduction of particle size of painting and coating particles is achieved by providing a tapered channel(s) (36, 36x) in the cylindrical wall (30) radially of the spray apparatus' nozzle head (14), which is a wall adjacent the nozzle outlet slit (34) of prior art apparatus As a novel application of the "Bernoulli Principle", its venturi feature achieves a movement and acceleration of ambient air to intermix with the paint particles being dispensed through the nozzle outlet slit (34). The tapered channel(s) (36, 36x) extends radially inwardly from an air inlet opening (38, 38x) on the exterior face of the wall (30), fully through the wall (30), and into a downstream air outlet opening (40, 40X) on the interior of the wall face, the tapering of the channel (36, 36x) being of a downstream size-reducing nature.

Selon l'invention, on obtient une amélioration (10, 12) avantageuse relative à la réduction de la dimension de particules de peinture et de revêtement, en ménageant un (des) canal (canaux) conique(s) (36, 36<u>x</u>) dans la paroi cylindrique (30) radialement par rapport à la tête de buse (14) de l'appareil de pulvérisation, ladite paroi étant adjacente à la fente (34) de sortie de la buse d'appareils actuels. En tant que nouvelle application du "principe de Bernouilli", la caractéristique venturi de ce principe déplace l'air ambiant et lui fait subir une accélération afin qu'il vienne se mélanger intimement avec les particules de peinture qui sont projetées au travers de la fente (34) de sortie de la buse. Le(s) canal (canaux) conique(s) (36, 36<u>x</u>) s'étendent radialement vers l'intérieur depuis l'ouverture d'arrivée d'air (38, 38<u>x</u>) sur la face externe de la paroi (30), et traversent toute la paroi (30) pour aboutir dans une ouverture (40, 40<u>x</u>) de sortie d'air en aval, sur l'intérieur de la face de la paroi, la conicité du (des) canal (canaux) (36, 36<u>x</u>) diminuant en dimension vers l'aval.
