Abstract
An air intake device with individual suction pipes having a variable effective length includes entry ports which are provided between a region of each of the suction pipes and a manifold. The entry ports can be closed by a closing device. The closing device is disposed outside a range of influence of the intake air flowing through the suction pipes, so that as a result no force which could move the closing device out of place is exerted on the latter. Air guide elements and air guide walls are provided in order to prevent the intake air from breaking away. The air intake device can be used in the intake pipe of an internal combustion engine.
