Abstract

UN INYECTOR DE COMBUSTIBLE (1) PARA UN MOTOR DE COMBUSTION INTERNA QUE COMPRENDE UN ALOJAMIENTO EXTERIOR (4) CON UNA BRIDA DE MONTAJE (2) EN SU EXTREMO POSTERIOR Y UNA TOBERA DE INYECCION (8) QUE SOBRESALE DEL ALOJAMIENTO POR SU EXTREMO DELANTERO, Y UN CONDUCTO DE PASO DE COMBUSTIBLE (34) QUE SE EXTIENDE POR EL CENTRO DEL INYECTOR. HAY UN HUSILLO (26) MONTADO EN LA PARTE EXTERIOR DE UN TUBO DE COMBUSTIBLE Y DENTRO DE UNA GUIA DEL HUSILLO (9) UN RESORTE DE CIERRE (21) POLARIZA EL HUSILLO HACIA ADELANTE EN LA DIRECCION DE CIERRE Y UN ANILLO DE EMPUJE (10) PRESIONA LA GUIA DEL HUSILLO HACIA ADELANTE POR DENTRO DEL ALOJAMIENTO DEL INYECTOR. EL TUBO DE COMBUSTIBLE CONSTITUYE UNA UNIDAD INDEPENDIENTE EN CONTACTO CON UN MIEMBRO DE VALVULA QUE HAY COLOCADO DETRAS DE EL A TRAVES DE UNA SUPERFICIE ANULAR (18) QUE ES SUSTANCIALMENTE PERPENDICULAR AL EJE LONGITUDINAL DEL INYECTOR. LA SECCION DELANTERA DEL HUSILLO (32) TIENE UN DIAMETRO EXTERIOR QUE ES COMO MUCHO 8 MI M MENOR QUE EL DIAMETRO INTERIOR DEL AGUJERO DE LA GUIA DEL HUSILLO (27) Y UN DIAMETRO INTERIOR QUE ES COMO MUCHO 8 MI M MAYOR QUE EL DIAMETRO EXTERIOR DE LA SECCION DELANTERA (24) DEL TUBO DE COMBUSTIBLE.
