ABSTRACT:
The device regulates the flow of exhaust gas reintroduced in the induction pipe in accordance with the conditions of utilization of the engine. It consists mainly in modifying a depression case the movable wall of which is connected by a cable to the closure member regulating the amount of gas re-cycled. This wall has an opening with which cooperates a valve subjected to the opposed actions of a spring which tends to apply it against its seat and a rod actuated by the butterfly valve member placed in the induction pipe. In this way there is provided a control which is independent of the characteristics of the various springs and is therefore more precise.
