Abstract

SE DESCRIBE UNA VALVULA QUE COMPRENDE UNA COMPUERTA (67) PARA UN CONDUCTO DE ESCAPE (63) DE LA CAMARA DE CONTROL (61) DEL INYECTOR; Y UN ELECTROIMAN (42) TIENE UN NUCLEO FIJO (46) CON UN ASIENTO (48) PARA UN CABLE (47) QUE ESTA EXCITADO PARA OPERAR LA ARMADURA (43) CONTROLANDO LA COMPUERTA. EL NUCLEO PRESENTA DOS PIEZAS POLO COAXIAL ANULARES (72,73), LA PIEZA EXTERIOR (72) QUE ES MAS CORTA QUE LA INTERIOR (73) SE FIJA CON UN ANILLO (76) DE MATERIAL ELECTROMAGENETICO QUE CIERRA PARCIALMENTE EL ASIENTO Y PERMITE UNA SUSTANCIAL REDUCCION EN EL DIAMETRO DE LA ARMADURA (43). EL DIAMETRO MENOR DE LA ARMADURA (43) HABILITA EL AJUSTE AL CUERPO (6) DEL INYECTOR MEDIANTE UNA TUERCA REDONDA (82) ATERRAJADA DE DIAMETRO MAYOR. LA ARMADURA (43), JUNTAMENTE CON UN RESORTE REACTIVO (89), SE AJUSTA EN UNA PLACA (84) QUE TIENE UN MANGUITO (83) PARA GUIA DEL VASTAGO (69); Y EL CONJUNTO SE AJUSTA DESPUES AL CUERPO (6), INDEPENDIENTEMENTE DEL ELECTROIMAN (42), ROSCANDO LA TUERCA REDONDA (82) DENTRO DE UN ASIENTO (93) EN EL CUERPO (6).
