Abstract

Perfeccionamientos en aparatos de freno para motores de combustión interna destinados a mover vehículos, del tipo de motor que comprende un turbosoplante y cuyo turbosoplante comprende una turbina acoplada al escape del motor, comprendiendo el turbosoplante además un compresor que movido por la turbina, alimentando la salida del compresor al colector de admisión del motor, y comprendiendo el motor un mecanismo para cambiar la secuencia normal de valvulaje del motor de modo que el motor funcione como compresor de aire cuando se desea frenar para frenar por lo tanto un vehículo movido por el mismo, caracterizados porque se dota de medios para aumentar la velocidad de rotación de la turbina del turbosoplante al reducirse la potencia del motor con el fin de aumentar el volumen de aire en el motor cuando se desea frenar y el motor funciona como compresor de aire.
