Abstract: A rotary atomizer spray painting device (10) having a nonconductive fixed, axial tube (20) for feeding paint, and having a nonconductive rotor (17) supported for rotation in a nonconductive housing (12) about the tube on air bearings or nonconductive ball bearings, and having turbine drive blades proximate one end thereof, the rotable rotor (17) supported inside of a nonconductive housing (12) which has a high voltage electrical path therethrough, electrically connected to one or more symmetrically spaced forwardly projecting needle electrodes (50), the rotable rotor being fixedly attached to a nonconductive forwardly projecting bell-shaped atomizer (14), the housing having pressurized air opening (38) for directing air in driving relationship to the turbine blades. The nonconductive design eliminates the danger of the atomizer picking up and storing high amounts of electrical energy, which poses a danger when such charged components inadvertently contact people or nearby objects.

Abstract: Un spray de peinture à atomiseur rotatif (10) possède un tube axial fixe non conducteur (20) pour amener la peinture, et un rotor non conducteur (17) supporté en rotation dans une enceinte non conductrice (12) autour du tube sur des paliers à air ou des paliers à billes non conductrices, et des aubes de turbine d'entraînement à une extrémité. Le rotor (17) est supporté à l'intérieur d'une enceinte non conductrice (12) qui possède un chemin électrique de haute tension, connecté électriquement à une ou plusieurs électrodes à aiguille se projetant vers l'avant et espacées de manière symétrique (50), le rotor étant fixé sur un atomiseur en forme de cloche non conducteur (14) l'enceinte ayant des ouvertures d'air pressurisées (38) pour envoyer de l'air vers les aubes de turbine et les entraîner. La conception non conductrice élimine le risque que l'atomiseur ne capte et emmagasine de grandes quantités d'énergie électrique ce qui constituerait un danger lorsque de tels produits ainsi chargés viendraient en contact de personnes ou d'objets environnants par inadvertance.
