Zusammenfassung:A tank venting apparatus for a supercharged internal combustion engine (1) has a fuel tank (18), a fuel vapour reservoir (25) connected to the fuel tank (18) via a connecting line (26) and to an intake pipe (9) of the internal combustion engine (1) via a venting line (27), a tank venting valve (28) which is arranged in the venting line (27), and a safety valve (33) which is arranged in the venting line (27) between the tank venting valve (28) and the intake pipe (9). The safety valve (33) is configured so as to permit a gas flow in a blocking direction (S) from the intake pipe (9) to the tank venting valve (28) with a certain positive pressure in relation to the pressure at the tank venting valve (28) is achieved in the intake pipe (9).
