Abstract

La valvola comprende un otturatore (67) per un condotto di scarico (63) di una camera di controllo (61) dell'iniettore, ed un elettromagnete (42) avente un nucleo fisso (46) ed un'ancora (43) mobile per controllare l'otturatore (67). L'ancora (43) è normalmente spinta da un molla di richiamo (86), in modo da tenere l'otturatore (67) in posizione di chiusura del condotto (63). Il dispositivo di registrazione della corsa dell'ancora (43) comprende un piatto (72), il quale viene fissato sul corpo (6), tramite un manicotto (41), con l'interposizione di due serie di rondelle calibrate (74). Il piatto (72) è munito di un elemento di arresto (76), contro cui si arresta un elemento di battuta (77) solidale con l'ancora (43), in modo da impedire il contatto dell'ancora (43) con il nucleo (46).
