Zusammenfassung:	The invention relates to techniques for spraying/projecting covering materials. The device forming the subject of the invention is characterised in that a cavity in the form of a truncated cone flaring in the direction of the flow is produced in the inlet portion of the body 1 of the device, the flow splitter 7 being made, on the front end of the barrel 6, in the form of a cone housed in the cavity 5 of the inlet portion 3 of the body 1 and being oriented by its apex in the direction opposite the flow and the means for the passage of the powder/air mixture through the body 1 and for its triboelectrical charging consisting in a plurality of channels 8 going from the front end to the rear end of the barrel 6 and formed between the internal wall of the body 1 and the wall of the barrel 6. The invention applies to the application of coverings of pulverulent materials having electrically-charged particles. L'INVENTION CONCERNE LES TECHNIQUES DE PULVERISATION-PROJECTION DE MATERIAUX DE REVETEMENT.LE DISPOSITIF FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QU'UNE CAVITE SOUS FORME D'UN CONE TRONQUE ALLANT EN S'EVASANT DANS LE SENS DU COURANT EST REALISEE DANS LA PARTIE D'ENTREE DU CORPS1 DU DISPOSITIF, LE DIVISEUR DE COURANT7 ETANT EXECUTE SUR L'EXTREMITE AVANT DU FUT6 SOUS FORME D'UN CONE LOGE DANS LA CAVITE5 DE LA PARTIE D'ENTREE3 DU CORPS1 ET ETANT ORIENTE PAR SON SOMMET EN SENS CONTRAIRE DU COURANT ET LE MOYEN POUR LE PASSAGE DU MELANGE POUDRE-AIR A TRAVERS LE CORPS1 ET POUR SA CHARGE EN TRIBO-ELECTRICITE CONSISTANT EN UNE PLURALITE DE CANAUX8 ALLANT DE L'EXTREMITE AVANT A L'EXTREMITE ARRIERE DU FUT6 ET FORMES ENTRE LA PAROI INTERIEURE DU CORPS1 ET LA PAROI DU FUT6.L'INVENTION S'APPLIQUE A L'APPLICATION DE REVETEMENTS DE MATIERES PULVERULENTES A PARTICULES ELECTRISEES.
