The invention relates to a device for admitting inlet gases and/or recirculated exhaust gases into an internal combustion engine cylinder, the device comprising a duct designed to supply said cylinder with inlet gases and/or with recirculated exhaust gases, characterized in that said device further comprises, in the duct, a flow control means that can be operated between a first position in which said duct supplies the cylinder with the inlet gases and a second position in which said duct supplies the cylinder with the recirculated exhaust gases. It also relates to the intake module and to the engine equipped therewith.

Device for admitting inlet gases and/or recirculated exhaust gases into an internal combustion engine cylinder

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 comprising at least one pipe which is arranged so as to supply the cylinder is disclosed. The control device comprises a means for sealing, and 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. 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, and a position of release of the means for deactivating.
