Abstract

In una nota valvola di iniezione il corpo di chiusura valvolare, costituito di un'ancora e di un otturatore valvolare e disposto all'interno di un portaugello, nell'ambito dell'ancora attraversa un anello di guida accoppiato rigidamente con un portaugello. L'ancora sul proprio intero contorno è guidata in un foro dell'anello di guida.La nuova valvola di iniezione possiede un portaugello 18 con almeno un nasello di guida (41) almeno in parte periferico. Il nasello di guida (42) è impresso in una parte di guida (40) del portaugello (18).La nuova valvola di iniezione è adatta specialmente per impianti di iniezione nel combustibile di motori endotermici a compressione di miscela e ad accensione indipendente (figura 1).
