Abstract

L'invention concerne une tête de pulvérisation à aspiration de produits chimiques qui comprend un canal (30) porteur présentant une entrée (12), une sortie (14) à travers laquelle s'écoule le fluide porteur et une chambre d'expansion (32) entre l'entrée et la sortie. Le pulvérisateur comprend également un canal d'alimentation en produits chimiques en communication fluidique avec la chambre d'expansion du canal porteur à travers une ouverture d'aspiration (49) et une conduite de purge (60) s'étendant du canal d'alimentation en produits chimiques entre l'ouverture d'aspiration et le produit chimique liquide, la conduite de purge étant connectée au canal d'alimentation en produits chimiques en communication fluidique avec l'air ambiant. Une soupape de commande (20) se trouve dans la tête de pulvérisation pour mettre simultanément en contact le canal porteur et la conduite de purge avec le canal porteur ouvrant et fermant sélectivement la conduite d'alimentation pour permettre à l'air ambiant de pénétrer de manière sélective dans le canal d'alimentation en produits chimiques en réaction à l'écoulement d'aspiration produit par l'écoulement du fluide porteur.
