System of air intake conduits for a combustion engine

The system housing has individual intake channels (3) and an exhaust return channel connected to the intake channels via valves. The system has a cover element (4) positioned on the housing (2) in such a way, that the return channel is defined between these two parts. The cover contains the valves formed as flat slide elements (11), and a drive mechanism, e.g. an electric motor (7) for the elements. Each intake channel has an exhaust intake (12) with flat seat (13), acting with the flat slide elements.
