Abstract

BOMBA ALTERNATIVA DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA. CONSTA DE LOS SIGUIENTES ELEMENTOS: UN EMBOLO DESPLAZABLE, DENTRO DE UN CILINDRO, POR ACCION DE UNA LEVA; UNA MARIPOSA A TRAVES DE LA CUAL SE SUMINISTRA EL COMBUSTIBLE AL CILINDRO; MEDIOS REGULADORES PARA AJUSTE DE LA MARIPOSA; PRIMEROS MEDIOS DE VALVULA EN COMUNICACION CON UN PUNTO INTERMEDIO ENTRE LA MARIPOSA Y EL CILINDRO; Y SEGUNDOS MEDIOS DE VALVULA PARA CONTROLAR LA PRESION APLICADA AL EXTREMO EXTERIOR DEL EMBOLO. CUANDO LOS PRIMEROS MEDIOS DE VALVULA SE ENCUENTRAN ABIERTOS, LA PRESION AGUAS ABAJO DE LA MARIPOSA SE REDUCE A UNA PRESION DE EVACUACION, CON LO QUE EL EMBOLO SE DESPLAZA HACIA DENTRO DEL CILINDRO POR LA PRESION DE SU EXTREMO EXTERIOR EN UNA CANTIDAD APROPIADA PARA ASEGURAR QUE NO PUEDA SER ACTUADO POR LA LEVA; LA PRESION DEL EXTREMO EXTERIOR ES SIEMPRE SUPERIOR A LA DE EVACUACION GRACIAS A LOS SEGUNDOS MEDIOS DE VALVULA.
