INTAKE PIPE WITH SHIFT DRUM

摘要

The invention relates to an intake pipe, notably for the intake air of an internal combustion engine, which comprises a shift drum for the preferably continuous adjustment of intake pipe length. Said intake pipe comprises a housing constructed of individual disks (24) which are joined in a sealing manner via ring grooves (40). The shift drum (12) is preferably made of regulator disks (29) so that it can be assembled without difficulty by alternately sliding a housing disk (24) and a regulator disk (29) on to the drive shaft (27). The intake channels are sealed by means of sealing lips (39) which are joined to the regulator disks (29), for example by injection, and are axially supported on annular ribs (27) forming part of the housing disks (24). This makes it possible to compensate for the tolerances of all components. Apart from being easier to assemble, an intake pipe constructed in the above manner also has a lower weight since no inserts are required to configure and seal the individual intake channels.
