Abstract

UN APARATO DE BOMBEO DE INYECCION DE COMBUSTIBLE DE DISTRIBUIDOR GIRATORIO TIENE UN PISTON TUBULAR DE BOMBEO (14) ACCIONABLE MEDIANTE UNA LEVA (16) PARA DESCARGAR COMBUSTIBLE A TRAVES DE UN CIRCUITO DE DESCARGA DE COMBUSTIBLE, A UN MOTOR. LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO SE DETERMINA MEDIANTE UNA VALVULA DE DESCARGA (26) QUE SE ACCIONA MEDIANTE UN CIRCUITO DE CONTROL DE FLUIDO QUE INCLUYE UN PISTON TUBULAR (25) MANEJADO TAMBIEN POR LA LEVA. UNA LANZADERA (40) SE MUEVE MEDIANTE EL COMBUSTIBLE DESPLAZADO POR EL PISTON AUXILIAR (25) HASTA QUE SE DEJA EN REPOSO Y EL AUMENTO DE PRESION ACCIONA LA VALVULA DE DESCARGA. SE PROPORCIONA UNA VALVULA (39) QUE CONETA EL CIRCUITO DE CONTROL Y EL CIRCUITO DE DESCARGA DE COMBUSTIBLE DURANTE EL MOVIMIENTO INICIAL DE LA LANZADERA.
