Abstract: A cap-free filler neck for a motor vehicle tank comprises a tubular part, which is connected to the tank, and an insert, which insert comprises a funnel part with a throat and a partition part adjoining the throat at the bottom. The upper edge zone of the funnel part and the partition part adjoin the tubular part in a sealing manner. The partition part has a throughflow opening which is closed in a sealing manner by a flap, which can be locked in a closed position, and can be pivoted into an open position counter to the force of a spring by a fuel nozzle. So that, despite the tight closure, rainwater which has penetrated can flow away, the space delimited by the tubular part, the funnel part and the partition part can be brought into connection with the environment via an opening in the tubular part, which opening can be closed by a valve, which is accommodated in said space, by the introduction of the fuel nozzle.

Abstract: A fuel tank with ventilation system and activated carbon filter which, on the one hand, is connected by a first line (22) to the fuel tank and by a second line (25) to an internal combustion engine, and, on the other hand, by a third line (26) to the atmosphere, should have as simple and compact a ventilation system as possible, which fulfills all functions in full measure. To this end, a controlled two-way valve unit (23) is provided, whereof the first path connects the first line (22) to the third line (26) and the second path connects the second line (25) to the third line (26), and an electronic control unit (28) is provided, which on the input side is connected to a refueling sensor (7) and to a liquid level sensor (13) and on the output side is connected to the controlled two-way valve unit (23).

Abstract: A fuel tank with an opening, on which a lid is mounted in a removable manner by means of thread or bayonet, is intended to provide a sustained and sealed closure under all conditions. For this purpose, two sealing rings are arranged between the sealing surfaces, the inner one being liquid-tight and the outer one being made of an elastomer with high permeation resistance. The sealing surfaces within the outer sealing ring have a narrow gap leading as far as the outer sealing ring, and the fuel tank has a reinforcement surrounding the opening.

Abstract: Multifunctional valve for the fuel tank of a motor vehicle. In order to fulfill all these requirements in terms of safety and the restriction of emissions with a valve in as simple a way as possible, the closing element (22) can be moved to a limited degree with respect the float (16), is acted on by a first spring (27) and has a small pressure equalization hole (25), an intermediate element (30) is provided on the float (16) and above the closing element (22) and can move to a limited degree with respect to the float (16) in the axial direction and is acted on by a second spring (35), and a seat plate (38) is arranged above the intermediate element (30) and is pressed downward against a second seat (43) by a third spring (39).

Abstract: A pressure control valve for a fuel tank with a spring-loaded valve body is intended to combine a maximum sealing effect with an unobstructed and reliable response. This is achieved in that the valve body comprises a foot part and a plate, the foot part being guided displaceably in the valve housing in the axis of symmetry, the plate having, in a staggered manner, a first groove and a second groove for holding a first sealing ring and a second sealing ring, the two sealing rings bearing against the sealing surface when the valve is closed and being flowed around in series when the valve is open.

Abstract: A closure stopper having a seal for a filler neck has first locking faces and a first sealing face, and the closure stopper has second locking faces and a second sealing face. The functions of the sealing ring and of the locking device are not impaired by the effects of temperature because (a) the smallest radius of the first sealing face is larger than the largest radius of the second sealing face, and (b) the sealing ring is a resilient circular ring with a first and a second sealing surface, of which, when the closure stopper is inserted, one surface bears against the first sealing face and the other face bears against the second sealing face. The sealing ring has a core made of resilient steel.

Abstract: A tank cap has a cap part, a filler neck for receiving a refueling nozzle wherein the neck can be closed by the cap part via a rotary closure having at least two seals arranged on the cap part and active between the cap part and the neck. The sealing surfaces on the neck are provided behind a raised region of a protuberance and below at least one projection.

Abstract: A filler pipe for the fuel tank of a motor vehicle having an internally located closure flap which closes a filling aperture at the end region of an internally located housing part made from plastic and can be brought into its open position by insertion of a fuel-pump nozzle in order to fill the fuel tank. An elastomeric seal is arranged on the housing part acting between the housing part and the closure flap. The seal is applied to a seal support which is connected to the plastic housing to provide a seal both relative to the closure flap and relative to the housing part.

Abstract: A filler neck for the fuel tank of a motor vehicle with a shutter which is mounted inside the filler neck and which can be actuated by the pump nozzle into an open position for filling the fuel tank and into a closed position via an actuating mechanism. The actuating mechanism of the shutter cooperates with a damping device during the closing movement in such a way that the shutter can be closed with a time delay.

Abstract: A metal fuel tank (1) with two tank shells (1a, 1b) which are welded together, an electrically driven fuel supply unit (2) inside the tank, and also with lead-in ducts for at least one metal fuel line (3) and for a connection device for supplying electricity to the fuel supply unit (2). The tank (1) is produced in such a way as to mount the fuel supply unit (2) from inside the tank (1) before the tank shells (1a, 1b) are welded together, and to have the lead-in ducts running through at respectively separated points through the tank shells (1a, 1b) which are created using gas-tight means of connection.
