Abstract

1. Dispositivo de control del flujo de los gases de escape para motores de combustión interna de dos tiempos, caracterizado por el hecho de estar constituido por una válvula parcializadora de un conducto principal de escape, puesta en la proximidad de la pared activa del cilindro, y por unos conductos de escape secundarios puestos en paralelo con el conducto principal de escape que tienen la sección útil variable de modo continuo, desde el cierre completo a la total apertura, por medio del accionamiento de dicha válvula parcializadora. 2. Dispositivo de control según la reivindicación precedente, caracterizado por el hecho de que dicha válvula parcializadora pone en comunicación con el conducto de escape principal al menos una cavidad resonante puesta en derivación con dicho conducto. 3. Dispositivo de control según las reivindicaciones precedentes, caracterizado por el hecho de que dicha válvula parcializadora se acciona de manera automática al variar la velocidad del motor. 4. Dispositivo de control del flujo de los gases de escape para motores de combustión interna de dos tiempos.
