Abstract

La valvola comprende un involucro tubolare (2), un elettromagnete (3) definito da un rocchetto tubolare (4) e da un avvolgimento elettrico (5), un corpo tubolare (6) una cui porzione (7) costituisce il nucleo del circuito magnetico definito nella valvola, un organo otturatore mobile (8) che controlla il passaggio di carburante attraverso un foro di iniezione (11), ed una ancora tubolare mobile (12) attirata dalla porzione (7) del corpo (6) quando l'elettromagnete (3) è eccitato determinando la corsa dell'organo otturatore (8). La principale caratteristica della valvola consiste nel fatto di comprendere un bloccaggio assiale fra l'involucro (2) ed il rocchetto (4), bloccaggio presentante almeno una linguetta (36) ricavata nell'involucro (2) ed una cavità (25) ricavata sul rocchetto (4) ed impegnata dalla linguetta (36).
