Bertrand, B

The device described comprises a recycling passage interconnecting the induction pipe and exhaust pipe of the engine. A valve for regulating the flow in the passage is controlled by the movable wall of a suction capsule. The inside of the capsule communicates with a suction take-off orifice in the induction pipe by way of a pipe in which there is inserted a chamber of a suction regulator. An opening in the chamber puts the latter in communication with the atmosphere and the opening cooperates with a valve member connected to a movable wall of the chamber. A spring connects the outside of the movable wall of the chamber to a mechanism controlling the butterfly valve member in such manner that the return force of the spring varies in the same direction as the opening of the butterfly valve member.
