Abstract

L'invenzione concerne un ugello iniettore di combustibili previsto per motori a combustione interna, con un portainiettore presentante un canale d'alimentazione di carburante e un canale di ricupero della nafta, la cui parte sovrastante del supporto ha una superficie di sostegno strutturata a guisa di cono d'accoppiamento su cui è compressa a tenuta stagna la parete interna di un raccordo anulare strutturata a guisa di superficie d'alloggiamento a forma di cono, il quale raccordo presenta una scanalatura anulare disposta nella superficie d'alloggiameto come collegamento di ricupero della nafta tra il canale di ricupero della nafta che sbocca sul cono d'accoppiamento e i tronchetti di ricupero della nafta sul raccordo.
