Abstract

Inlet pipes extend from a collector to the cylinder inlets of the internal combustion engine. The inlet pipes are formed with mutually facing openings in their adjacent walls. Control flaps each have a shaft, which is respectively provided with a damping element and is mounted by way of the damping elements in a bearing bush. The openings in the inlet pipes are selectively closed and opened with the control flaps.
