Abstract

BOMBA DE INYECCION DE COMBUSTIBLE PARA MAQUINAS DE COMBUSTION INTERNA. LA BOMBA DE INYECCION DE COMBUSTIBLE PRESENTA UN EMBOLO DE BOMBA (12) QUE TRABAJA EN UN TALADRO CILINDRICO (10) DE UN CASQUILLO CILINDRICO (11). EN EL TALADRO CILINDRICO (10) ESTA LIMITADA UNA CAMARA DE TRABAJO DE LA BOMBA (40) POR EL EMBOLO DE LA BOMBA (12), POR UN LADO, ASI COMO UNA VALVULA CONTROLADA ELECTRICAMENTE (32) POR OTRO LADO. MEDIANTE LA VALVULA (32), LA CAMARA DE TRABAJO DE LA BOMBA (40) SE PUEDE UNIR EN LA CARRERA DE ASPIRACION DEL EMBOLO DE LA BOMBA (12) Y PARA EL CONTROL DE LA CARRERA DEL EMBOLO DE LA BOMBA QUE ACTIVA LA INYECCION, CON UNA CAMARA DE ASPIRACION (18). EL CASQUILLO CILINDRICO (11) ESTA RODEADO PARCIALMENTE POR UNA CAMARA ANULAR (41), A TRAVES DE LA QUE FLUYE EL COMBUSTIBLE ENTRE LA CAMARA DE TRABAJO DE LA BOMBA (40) Y LA CAMARA INTERIOR (18). DE LA CAMARA ANULAR (48) SE RAMIFICA UN BYPASS (43), A TRAVES DEL QUE FLUYE EL COMBUSTIBLE A OTRA CAMARA ANULAR (48) QUE RODEA PARCIALMENTE A LA VALVULA (32). LA CAMARA ANULAR (48) ESTA DESCARGADA MEDIANTE UNA TUBERIA DE RETORNO HACIA EL DEPOSITO DE COMBUSTIBLE. LAS DOS CAMARAS ANULARES (41, 48) ESTAN ATRAVESADAS CONTINUAMENTE POR COMBUSTIBLE COMO CONSECUENCIA DE LA PRESION QUE IMPERA EN LA CAMARA INTERIOR (18), DE MANERA QUE SE CONSIGUE UNA REFRIGERACION DE LA CAMARA DE TRABAJO DE LA BOMBA (40) ASI COMO DE LA VALVULA (32).
