Abstract

PROCEDE ET DISPOSITIFS PERFECTIONNES POUR LA PULVERISATION HYDROSTATIQUE EN JET ROND D'UN LIQUIDE CHARGE ELECTROSTATIQUEMENT. LE DISPOSITIF DE PULVERISATION 101 POSSEDE UN CANON DE PROJECTION 102 AVEC UNE BUSE CENTRALE QUI DONNE UN JET A VORTEX HYDROSTATIQUE 103. UN VORTEX PNEUMATIQUE AUXILIAIRE 104 EST FORME AUTOUR DU VORTEX 103 POUR ELIMINER DES ANOMALIES DE DISTRIBUTION DE LIQUIDE. ON OBTIENT UN REGLAGE DE L'OUVERTURE DU VORTEX 103 EN MODULANT LE DEBIT DU VORTEX PNEUMATIQUE, TOUTEFOIS SUPERIEUR AU DEBIT NECESSAIRE A LA CORRECTION DES ANOMALIES, PAR OUVERTURE AJUSTEE DE LA VANNE DE FUITE 114. APPLICATION A LA PEINTURE PAR PROJECTION ELECTROSTATIQUE.
