Abstract
In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.
Claims8
A filling pipe for filling a fuel tank, which has an antisurge tower, wherein the filling pipe has a branching element comprising an opening in a wall of the pipe, the opening being designed to divert a first subflow of fuel into the antisurge tower and a second subflow into the fuel tank, and wherein the branching element is designed in such a manner that when there is a small inflowing volume flow, the antisurge tower is fed first of all.
