Abstract
An adjustable intake pipe, especially for supplying combustion air to an internal combustion engine, which includes a collector chamber arranged in an essentially cylindrical control element. The collector chamber has a larger volume than required for the air supply, so the chamber is not used efficiently. In the invention, the collector chamber volume is used by arranging additional components of the intake tract defined by the intake pipe, i.e. of an internal combustion engine, within the collector chamber (11), for example, by arranging a resonance chamber (20) therein with the resonance chamber connected to the air supply system by through holes (19). This arrangement better utilizes the chamber volume and is particularly advantageous in motor vehicle engine compartments where limited space is available. The intake system also is more compact and has a lower overall weight.
