Abstract: In the case of a filling device for a motor vehicle fuel tank, a distributing element extends from a filling nozzle to an anti-surge tower of the motor vehicle. When there is a low volume flow of fuel in the filling nozzle, the distributing element supplies all of the fuel to the anti-surge tower. When there is a large volume flow, the greater part of the fuel passes directly into the fuel tank. It is thereby ensured that during an initial filling or emergency filling with a jerrycan, virtually all of the fuel passes into the anti-surge tower.
