Abstract
The invention relates to a valve and a fuel tank provided with a valve for a motor vehicle. Bleeder valves for integrated compensation volumes for fuel tanks are known in the prior art. One disadvantage of known valves is that if the tank is filled slowly during the refueling operation, the fuel compensation volume can fill. The invention aims to provide a valve with a compact construction. To this end a pressure valve ( ) is located on the valve ( ) which opens if there is a predetermined excess pressure in the fuel tank ( ), a refueling venting opening ( ) is configured in the valve ( ) so that a sealing plate ( ) can close the refueling venting opening. The sealing plate ( ) has an operational venting opening ( ), which can be closed by a displaceable closure element ( ) that is displaced according to a position of a float ( ) that is located on a float lever ( ).
