Abstract
1. A fuel tank (1) having a filler neck (3) closable by a filling flap (2), the volatile fuel components (5) located in free space (4) of the fuel tank (1) being able to be fed into a storage chamber (7) filled with an absorption element (6), including a vent line (8) that connects the free space (4) to the storage chamber (7) and is closable by a valve (9). The filler neck (3), on the side facing away from the fuel tank (1), has a plug fitting (10) with a valve support (11). The valve (9) includes a sealing flap (12), the sealing flap (12) and the filling flap (2) forming components of the valve support (11), each being able to pivot about a shaft (13,14), and, being acted upon by spring tension, each being able to be placed against a valve seat (15,16) in the valve support (11). The sealing flap (12) and the filling flap (2) are mechanically coupled by a driving device (17) and are able to be forced jointly into the open position by inserting a gas hose nozzle (18) through the filling flap (2) into the filler neck (3).
