L'invention a pour objet une buse pulvérisatrice comportant
un opercule percé d'un étroit orifice et un noyau axial interne, les
faces en regard de ces deux pièces coopérant pour former un système de
canaux tourbillonnaires alimentant l'orifice, et incorporant dans une
chambre en amont un clapet (4) à cupule circulaire de concavité tournée
vers l'aval que porte un tronc de guidage axial, guidé latéralement,
mobile axialement et servant ici de noyau.
Cette buse est utilisable sur tout vaporisateur, notamment
miniature, que l'on désire rendre étanche, son nombre de pièces est
réduit à deux et leur montage simple, ce qui conduit à une fabrication
d'un prix de revient particulièrement avantageux.
