Abstract

UNA BOQUILLA DE INYECCION DE COMBUSTIBLE DEL TIPO DE ABERTURA EXTERNA TIENE UNA PIEZA VALVULA (16) QUE SE MUEVE HACIA FUERA POR LA PRESION DEL COMBUSTIBLE EN EL INTERIOR DEL TUBO (15) EN EL CUERPO DE LA BOQUILLA (10). LA PIEZA VALVULA SE DESVIA HACIA LA POSICION DE CERRADO MEDIANTE UNA PIEZA ELASTICA EN FORMA DE VARILLA (18) FORMADA INTEGRAMENTE EN LA PIEZA DE VALVULA Y QUE SE EXTIENDE EL INTERIOR DEL TUBO . EN EL EXTREMO LEJANO CON RESPECTO A LA CABEZA DE LA VALVULA, EL ANILLO SE ENGRANA CON UN COLLAR ENTRE EL CUAL Y UNA PIEZA ADYACENTE DEL CUERPO DE LA VALVULA, HAY UN DIAFRAGMA (21). EL GROSOR DEL DIAFRAGMA ES SELECCIONADO DE MODO QUE LA FUERZA DE TRACCION EN LA VARILLA SEA SUPERIOR A LA NECESARIA PARA PROPORCIONAR LA PRESION DE APERTURA DE LA BOQUILLA DESEADA, Y ESTO SE AJUSTA AL VALOR DESEADO MEDIANTE LA COMPRESION DE UNA PARTE DEL CUERPO DE LA BOQUILLA UTILIZANDO UN CAPUCHON ROSCADO (24) QUE ASEGURE EL CUERPO DE LA BOQUILLA A UNA PIEZA DE SOPORTE.
