The intake pipe has a dimensionally stable intake pipe body with a passthrough opening, and a positioning element arranged in the passthrough opening to change the area of flow cross section. The positioning element is constructed of a nonreturn valve opening only toward the internal combustion engine, the nonreturn valve comprising a sealing element and a sealing seat which can move relative to one another and which can be brought, as required, into engagement with one another to close off the passthrough opening.
