The device of the recirculation of exhaust gases of a diesel engine having a valve controlled by depression, by a plug of a faucet iintermediaire.

摘要

The device includes a valve (30) interposed on an exhaust gas recirculation pipe (28) including a stopper (30a) connected to a flexible membrane (30c) delimiting a leaktight chamber (30d). The leaktight chamber (30d) may be placed in communication with a vacuum source (31), in order to cause the opening and closure of the valve (30). Adjustment of the vacuum in the chamber (30d) is carried out as a function of operating parameters of the engine. The device includes, interposed on a connection pipe (32) between the vacuum source (31) and the chamber (30d) of the valve, a device (40) for causing the opening and closure of the connection pipe (32) including a tap cock connected, for its movement between an open position and at least one closed position of the connection pipe (32), to a movable member for controlling and adjusting the level of power of the engine (25).
