Abstract

UN INYECTOR DE COMBUSTIBLE PERFECCIONADO QUE CONSTA DE UN EMBOLO (1) PARA CONTROLAR EL PASO DE COMBUSTIBLE ENTRE UNA CAMARA DE INYECCION (3) Y AL MENOS UN ORIFICIO DE INYECCION (4) FORMADO EN UNA TOBERA DE INYECCION (5); Y UNA VALVULA DE MEDIDA DE COMBUSTIBLE ELECTROMAGNETICA (6) PARA CONTROLAR EL PASO DE COMBUSTIBLE A TRAVES DE UN ORIFICIO DE DRENAJE (7) ENTRE UNA CAMARA DE CONTROL (8), A LA QUE SE SUMINISTRA COMBUSTIBLE A PRESION, Y UNA CAMARA DE BAJA PRESION, PARA REDUCIR LA PRESION DEL COMBUSTIBLE HASTA UN VALOR DADO DENTRO DE LA CAMARA DE CONTROL (8) Y PARA DESPLAZAR ASI EL EMBOLO (1). EL COMBUSTIBLE A PRESION SE SUMINISTRA A LA CAMARA DE INYECCION (3) Y A LA CAMARA DE CONTROL (8) POR MEDIO DE UN ACCESORIO SIMPLE (13) CONECTADO A UNA TUBERIA DE SUMINISTRO (14) Y QUE ENTRA EN EL INTERIOR DE UN ORIFICIO DE SUMINISTRO (15) FORMADO EN EL CUERPO DEL INYECTOR (2) Y QUE COMUNICA CON LA CAMARA DE CONTROL (8) Y CON UN CONDUCTO DE SUMINISTRO DE COMBUSTIBLE A LA CAMARA DE INYECCION (3) Y QUE CONSTA DE UNA CAMARA ANULAR (25) Y UN ORIFICIO RADIAL (26) FORMADO EN UN MANGUITO (16) ALOJADO EN UN ORIFICIO (19) DEL CUERPO (2).
