Abstract

La valvola (5) è comandata da una valvola elettromagnetica di dosaggio (41), comprendente una testa (49) avente una camera di comando (56), un condotto di ingresso (57) ed un condotto di scarico (58). La testa (49) è inoltre munita di una cavità (67) in comunicazione con il condotto di ingresso (57), nella quale viene guidata una porzione (68) dell'equipaggio mobile (8, 28) di chiusura del foro di iniezione (11), in modo tale, che durante l'iniezione la porzione (68) parzializza il condotto di ingresso (57). Questo è in comunicazione con una camera di ricezione (59) disposta tra una sede di ricezione (51) del corpo (6) della valvola (5) e la superficie esterna di un'appendice (54) della testa (49). L'equipaggio (8, 28) viene spinto in posizione di chiusura dall'azione combinata della pressione ai suoi capi e di una molla (37) disposta in vicinanza di una camera di iniezione (19).(Figura 1)
