Abstract

LA VALVULA COMPRENDE UN REGISTRO (67) PARA EL CONDUCTO DE DESCARGA (63) DE LA CAMARA DE CONTROL (16) DEL INYECTOR; Y UN ELECTROIMAN (42) QUE TIENE UN NUCLEO FIJO (46) Y UNA ARMADURA (43) QUE CONTROLA EL REGISTRO (67), Y QUE NORMALMENTE SE IMPULSA POR UN RESORTE REACTIVO (86) PARA MANTENER EL CONDUCTO DE DESCARGA (63) CERRADO POR EL REGISTRO (67). EL DISPOSITIVO PARA AJUSTAR EL RECORRIDO DE LA ARMADURA (43) COMPRENDE UNA PLACA (72) QUE SE AJUSTA AL CUERPO (6) DEL INYECTOR MEDIANTE UN MANGUITO (41), Y A TRAVES DE LA INTERPOSICION DE DOS JUEGOS DE ARANDELAS CALIBRADAS (74). LA PLACA (72) TIENE UN ELEMENTO DE TOPE O RETENCION (76), CONTRA EL CUAL SE DETIENE UN ELEMENTO DE CONTACTO (77) INTEGRAL CON LA ARMADURA (43), PARA EVITAR QUE LA ARMADURA (43) CONTACTE CON EL NUCLEO (46).
