Devices for re-cycling the exhaust gases of an internal combustion engine

摘要

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.
