    摘要: A tank ventilation device for a motor vehicle includes a ventilation line, connected on one side to an accumulator for gaseous hydrocarbons and connected on another side via a connection to a filling tube for filling a tank of the motor vehicle, wherein the ventilation line is connected to the tank so that gaseous hydrocarbons which are displaced during refueling are re-circulated toward the connection via the ventilation line, a device for applying a pressure on the ventilation line for carrying out a leakage test of the tank ventilation device, when the filling tube is closed with a closure device, and a float body provided in a region of the connection of the ventilation line to the filing tube for preventing entering of liquid fuel into the ventilation line.
