Abstract

L'invention concerne un appareil de charge de poudre pour appareil de peinture électrostatique à la poudre. Cet appareil comprend un conduit 1 pour transporter de la poudre en suspension dans un gaz, une chambre annulaire d'électrodes 2a à l'extérieur du conduit et communiquant avec celui-ci par une fente 2b, une électrode annulaire 3 disposée à l'intérieur de la chambre d'électrode 2a, une électrode à décharge de couronne 4 disposée au centre du conduit, des moyens d'introduction de gaz dans le conduit à travers la fente et des moyens 12 permettant d'appliquer une tension entre les électrodes de façon que l'électrode à décharge de couronne 4 engendre une décharge unipolaire de couronne en direction de l'électrode annulaire 3. L'invention s'applique à la peinture
