Abstract
A fuel filler device for filling fuel into a vehicle tank, includes a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank. At least one pivotably mounted closing flap is arranged in the filler pipe. A spring element is provided, which biases the at least one closing flap into a closing position closing a passage through the filler pipe. The at least one closing flap is pivotable from the closing position into an opening position opening a passage through the filler pipe as a result of the fuel filler nozzle inserted into the filler pipe. At least one valve element forms at least one bypass to the at least one closing flap, and from a limit pressure difference, allows a passage of gas out of the filler pipe and/or into the filler pipe.
