Fuel tank for storing e.g. petrol, in front refueling motor car, has tank inlet valve that is lockable during refueling when fuel in tank reaches preset level, where tank inlet valve is opened after termination of refueling

摘要

The tank (1) has a tank inlet valve (V1) that is lockable during refueling when the fuel in the tank reaches a preset level (S1), where the tank inlet valve is opened when refueling of the tank is terminated. A tank ventilation valve (V2) is arranged at a tank ventilation (4) and acts on the fuel tank with low pressure. A tank flap sensor (13) is arranged at a tank flap (12). The tank inlet valve is openable only when an igniter (11) is deactivated. A pressure sensor monitors the air pressure ratio inside the fuel tank.
