Abstract

Projecteur électrostatique rotatif de produit de revêtement, installation de projection comprenant un tel projecteur et procédé de revêtement au moyen d’un tel projecteur Ce projecteur électrostatique rotatif de produit de revêtement comprend un bol de pulvérisation, un corps (102) et une turbine d’entraînement montée dans le corps et configurée pour entraîner le bol de pulvérisation en rotation autour d’un axe de rotation (A100) défini par le corps Le projecteur comprend également des électrodes (140) de charge du produit de revêtement pulvérisé par le bol de pulvérisation, ces électrodes étant montées sur une bague (160) rapportée sur le corps, et une jupe (124) d’éjection d’air autour du bol. Une fente annulaire (232) est définie radialement entre la bague (160) et la jupe (124) avec sa sortie (234) dirigée vers l’avant du projecteur. Figure pour l'abrégé : 5
