Abstract

L'INJECTEUR EST DU TYPE COMPORTANT UN CORPS D'INJECTEUR 1, UNE AIGUILLE CREUSE 2 ET UNE SECONDE AIGUILLE 5 COULISSANT DANS LA PREMIERE ET PROLONGEE PAR UN TETON 11, UN TROU D'INJECTION 10 COINCIDANT AVEC L'AXE DE L'INJECTEUR. POUR AVOIR UNE PULVERISATION FINE EN FAIBLE REGIME ET UN JET COMPACT EN REGIME FORT, A L'ETAT FERME OU PARTIELLEMENT OUVERT, LE TETON 11 PLONGE AVEC JEU DANS LE TROU ET L'AIGUILLE CREUSE 2 PRESENTE A SON EXTREMITE TOURNEE VERS L'OUVERTURE UNE COLLERETTE CONIQUE 3 DONT LA SURFACE EXTERIEURE FORME UN SIEGE D'ETANCHEITE POUR L'AIGUILLE CREUSE ET LA SURFACE INTERIEURE UN SIEGE D'ETANCHEITE POUR LA SECONDE AIGUILLE.
