Abstract

DISPOSITIVO DE INYECCION DE COMBUSTIBLE QUE TRABAJA SEGUN EL PRINCIPIO DE ACUMULACION DE ENERGIA DE CUERPOS SOLIDOS Y QUE ESTA CONFORMADO COMO UNA BOMBA ALTERNATIVA DE EMBOLO CON UN ELEMENTO DE EMBOLO IMPULSOR (35, 24), QUE ACUMULA ENERGIA CINETICA DURANTE UNA FASE DE ACELERACION PRACTICAMENTE SIN RESISTENCIA, LA CUAL SE TRANSMITE BRUSCAMENTE AL COMBUSTIBLE QUE SE ENCUENTRA EN UNA CAMARA DE COMPRESION (66), DE MANERA QUE SE PRODUCE UNA PRESION PULSATORIA PARA INYECTAR COMBUSTIBLE A TRAVES DE UN DISPOSITIVO DE TOBERA DE INYECCION. EL MEDIO QUE INTERRUMPE LA FASE DE ACELERACION SIN RESISTENCIA ES UNA VALVULA QUE CONTIENE UN CUERPO DE LA VALVULA (50A) Y UN ASIENTO DE LA VALVULA (57) CONFORMADO EN EL ELEMENTO DE EMBOLO IMPULSOR Y QUE CIERRA LA CAMARA DE COMPRESION (66) PARA PRODUCIR LA PRESION PULSATORIA, CON LO CUAL LA ENERGIA CINETICA DEL ELEMENTO DE EMBOLO IMPULSOR (35, 24) ES TRANSMITIDA AL COMBUSTIBLE ENCERRADO EN LA CAMARA DE COMPRESION (66). EL ASIENTO DE LA VALVULA (57) Y EL CUERPO DE LA VALVULA (50A) ESTAN DISPUESTOS EN EL EXTREMO DEL ELEMENTO DE EMBOLO IMPULSOR (35, 24) QUE SE ENCUENTRA DELANTE EN LA DIRECCION DE INYECCION, DE MANERA QUE LA CAMARA DE COMPRESION (66) ESTA CONFIGURADA DE FORMA QUE ESTA SEPARADA ESPACIALMENTE DEL ELEMENTO DE EMBOLO IMPULSOR (35, 24).
