Abstract

Iniettore (1) monogetto assistito ad aria in cui un otturatore (11), mosso da un otturatore elettromagnetico (7), controlla la formazione di getti di combustibile attraverso fori di atomizzazione (15) contenuti in un elemento erogatore (5), a valle del quale è disposta una camera (21) di atomizzazione ausiliaria, delimitata internamente almeno in parte da una superficie (24b) tronco-conica nella quale sboccano fori radiali (25) per l'adduzione di un flusso di aria ausiliaria presentanti rispettivi assi ortogonali alla superficie (24b) stessa..(Figure 1 e 2).
