Abstract
An intake system (10) of an internal combustion engine includes an intake manifold (12) with at least two feed pipes (14) connected with cylinder head intake ports of the internal combustion engine and includes at least one intermediate chamber (30) having connections (34) to an interior volume (24) of each feed pipe (14). Each connection (34) can be opened or closed by way of an intake control valve (49) having a switch chamber (48) which has a connection (60, 62) to means for creating a pressure in the switch chamber (48). The switch chamber (48) is separated from the interior volumes (24) of the feed pipes (14) and the intermediate chamber (30) by a diaphragm (50).
