  • Ventilation and/or pressure-equalizing system for a fuel tank
    Patent number: 6871662
    Abstract: A ventilation and/or a pressure-equalizing system for a fuel tank, in particular for a fuel tank of a motor vehicle, includes at least one aeration and/or de-aeration line leading into the fuel tank, via which the gases and/or vapors may be removed from or conducted into the fuel tank. A collection device for liquid fuel is coupled into the aeration and/or de-aeration line, the collection device including at least two chambers, of which one is used as a temporary storage device for liquid fuel and is connected to a return line into the fuel tank.
    Type: Grant

  • Fuel tank system especially for motor vehicles and method for controlling and monitoring said system
    Patent number: 6289947
    Abstract: The invention relates to a method for filling a fuel tank (2) with a filling conduit (4). The fuel flow entering the tank is directed by a through flow sensor (53) in order to control and monitor the filling process. A particularly suitable tank system (1) for implementation of said method comprises a fuel tank (2), a filling tube (3) surrounding a filling conduit (4) and discharging into said fuel tank, an adsorption filler (6) connected to the gas area (8) of the tank (2) and a through-flow sensor (53) which detects the flow of fuel in the filling tube (2).
