Abstract
In motor vehicles with an onboard refueling vapor recovery (ORVR) system, a filling pipe with a reduced cross-section is provided. The pipe portion with reduced cross-sectional area has at least one longitudinally directed bead which gradually merges into the adjoining cylindrical regions to reduce flow resistance and prevent turbulent flow. The bead can be produced without impairing the strength of the filling pipe. When two or more beads are provided, they are preferably distributed equiangularly.
