Abstract
UNA BOMBA DE INYECCION DE COMBUSTIBLE DEL TIPO DISTRIBUIDOR TIENE UN REGULADOR DE VELOCIDAD DE REVOLUCION (22) EN UNA CAMARA INTERIOR DE BOMBA (18) BAJO PRESION DE CONTROL QUE ACTIVA UN COMPONENTE DE CONTROL DE MEDICION DE LA INYECCION (21) Y UN DISTRIBUIDOR DE INYECCION HIDRAULICO (30) COMUNICANDO CON LA CAMARA DE BOMBA INTERNA (18) QUE ESTABLECE EL COMIENZO DE LA INYECCION (SB) A "AVANZANDO" CUANDO SE INCREMENTA LA PRESION DE CONTROL EN LA CAMARA DE BOMBA INTERNA (18) Y A "RETARDADO" CUANDO FALLA. PARA OBTENER UN COMIENZO DEPENDIENTE DE LA CARGA DE ALIMENTACION (LFB) UN MANGUITO DE REGULACION (40) DEL REGULADOR DE VELOCIDAD (22) CONTROLA UN REGULADOR DE CARGA (45) EN LA CAMARA DE BOMBA INTERNA (18) QUE DEPENDE DE LA CARGA, LA CUAL, DEPENDIENDO DE LA POSICION REGULACION (40), LIBERA UNA SECCION CRUZADA DE REGULADOR VARIABLE A UN CANAL DE DESCARGA (46). PARA OBTENER UN GAS DE ESCAPE LIMPIO DE TODOS LOS NIVELES DE CARGA, EL REGULADOR DE DESCARGA (45), ESTA CONSTRUIDO EN FORMA TAL QUE LA SECCION CRUZADA LIBRE DEL REGULADOR ES CERO O MUY PEQUEÑA EN UNA POSICION (VL) ASUMIDA POR EL MANGUITO REGULADOR (40) EN CARGA COMPLETA, GRANDE EN UNA POSICION DE CARGA PARCIAL (TL) Y OTRA VEZ MAS PEQUEÑA EN CARGA CERO O POSICION EN VACIO (NL). ASI, EL COMIENZO DE LA INYECCION (SB) SIN CARGA ES PUESTO EN "AVANCE" COMO CONTRA LA CARGA PARCIAL, PERO NO TAN AVANZADO COMO EN UNA CARGA TOTAL.
