ABSTRACT:
An air-intake device having a variable induction-pipe length for an internal combustion engine includes a cylindrical collector. Induction pipes extend from inlets on the collector along a periphery of the collector up to inlet ducts of an internal combustion engine. A switching device in the shape of a cylinder sector is pivotably mounted in the collector. In a first rotary position, the switching device closes lead-in ports which connect the induction pipes to the collector. Therefore, the switching device has elevations on its lateral surface. The elevations have a front surface and adjoining side walls together forming a first contact surface in a closing direction, and an end region opposite the front surface forming a second contact surface. The first and second contact surfaces have a seal and bear against first and second bearing surfaces of the lead-in ports in the first rotary position, for tightly closing the lead-in ports.
