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).

Abstract: A dispensing nozzle seal that can be inserted into the filler neck of a fuel tank. The nozzle seal has a sealing ring made of elastomeric material with a sealing lip that is configured to sealingly surround with a degree of elastic prestressing a dispensing nozzle that is inserted into the filler neck. The sealing ring is joined to a seal support tapering conically in the direction of the fuel tank. The seal support is constructed in one piece, and is connected frictionally or with form locking to the sealing ring.
