Embodiment Construction

[0023] figure 1 The area of ​​a fuel tank device 1 for a motor vehicle is shown, which is not shown in detail here. The motor vehicle has an internal combustion engine, and the fuel temporarily stored in the fuel tank 2 can be fed into the internal combustion engine through a fuel line not shown here. For example, the fuel can be fed into the fuel tank 2 through the filling line 3 by means of a fuel gun 4, and the fuel gun can be inserted into the filling line 3 through the filling port 5 of the filling line 3. The fuel tank device 1 also has a fuel tank ventilation device 6 having a fuel tank ventilation line 7. A flow connection between the fuel tank 2 and the filter device 8 can be established via the fuel tank ventilation line 7. This flow connection can be adjusted by a fuel tank vent valve 9 arranged in the fuel tank vent line 7, that is, for example, it can be opened or interrupted. Two non-return valves 10 and 11 are connected in parallel with the fuel tank vent valve...

Description

Technical field [0001] The invention relates to a fuel tank device for a motor vehicle, which has a fuel tank, a filling pipe connected to the fuel tank, and a fuel tank ventilation device. The fuel tank ventilation device has a fuel tank ventilation device connected to the fuel tank. Valve of the fuel tank ventilation line. The invention also relates to a motor vehicle and a method for operating a fuel tank device. Background technique [0002] Fuel tank devices of the aforementioned type are known from the prior art. It includes a fuel tank for supplying or temporarily storing fuel for the internal combustion engine of a motor vehicle. That is, for example, the fuel tank is connected to the internal combustion engine through a fuel line. For example, a filling pipe with a filling nozzle or a filling pipe designed as such is used to fill the fuel tank with fuel, in particular by the driver of the motor vehicle. In modern motor vehicles, the fuel tank usually exists as a pres...
