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).The valve comprises a tubular casing (2), an electromagnet (3) defined by a tubular spool (4) and an electric winding (5), a tubular body (6) whose portion (7) forms the core of the magnetic circuit defined in the valve, a mobile shutter member (8) which controls the passage of fuel through an injection hole (11), and a mobile tubular anchor (12) attracted by the portion (7) of the body (6) when the electromagnet ( 3) is excited by determining the stroke of the shutter member (8). The main characteristic of the valve consists in the fact of comprising an axial locking between the housing (2) and the spool (4), locking having at least one tab (36) obtained in the housing (2) and a cavity (25) obtained on the spool (4) and engaged by the tab (36).
