Abstract

L'invention concerne un dispositif de pulvérisation de dispersions comportant une tête de pulvérisation munie d'une buse. Dans le dispositif selon l'invention, un pointeau 4, logé à l'intérieur de la tête de pulvérisation 1, est monté de maniere à pouvoir être amené devant l'ouverture de la buse 3; l'extrémité du pointeau, côté buse, est de forme conique, avec un angle de cône de 15 degrés à 90 degrés , la partie intérieure de la buse étant adaptée à la pointe du pointeau. Le pointeau est déplaçable longitudinalement de façon à être en position rétractée durant la pulvérisation, et à être amené devant l'ouverture de la buse 3 dès que le débit du mélange en dispersion s'abaisse à une valeur indésirable. Une pièce d'insertion formant tamis et un organe racleur sont prévus entre l'ouverture d'amenée du mélange et la buse. Applications : pulvérisation de dispersions notamment de suspensions contenant du graphite.
