Abstract
A fuel-filler inlet for motor vehicles comprises a closure neck, an insert associated with the closure neck, a filling chamber downstream of the insert, and a filling tube downstream of the filling chamber which leads to a fuel tank. In order to achieve good guidance of the fuel nozzle, reliable response of the expansion port and ventilation during the fuel-dispensing operation, a collar is provided between the filling chamber and filling tube, the internal diameter of which is somewhat larger than that of the opening tube of a fuel nozzle. The collar provides through-passage openings which, with the fuel nozzle inserted, produce a flow connection between the filling tube and filling chamber.
