Claim:
1. A control device for a flow of intake gas and/or recirculated exhaust gases in a cylinder of an internal combustion engine, and for an intake module (M) comprising at least one pipe which is arranged so as to supply the cylinder with intake gas (F) and/or recirculated exhaust gases (EGR), the control device comprising: a means for deactivating at least one pipe which is able to be controlled between a first position in which the pipe supplies the cylinder with the intake gases (F) and a second position in which the pipe supplies the cylinder with the recirculated exhaust gases (EGR), and a means for sealing configured to hermetically close an opening of the pipe for the inlet of exhaust gases, wherein the means for sealing is configured so as to be displaced as a result of the difference in pressure between the intake and the exhaust on both sides of the means for sealing, between: a locked position of the means for deactivating in the first position when the pressure at the exhaust is higher than the pressure at the intake, and a position of release of the means for deactivating when the pressure at the exhaust is lower than the pressure at the intake.
