Abstract: A fuel tank made of plastic, in the interior of which an insert (2) is located, wherein the insert should enclose a space (3), wherein the fuel tank should offer the greatest possible economy of space, and the fuel tank and the insert should have a simple form. For this purpose, a box made of plastic and open at the top is attached to the inside of the upper wall (1) of the fuel tank as an insert (2), wherein the box forms a closed space (3) together with the wall (1) of the tank, wherein the insert (2) comprises a bottom (5) and side walls (6, 7, 8, 9), the upper edges of which are connected in a bonded manner to the wall (1) of the tank. The insert (2) contains inner parts (20-26) that are integral therewith and has at least one fitting (13-16) on the side walls (6, 7, 8, 9) for connecting a pipe line.

Abstract: In a tank system, a venting line (6) connects the fuel tank to an activated carbon filter, and a recirculating line (10) opens into a filler head (3). In order to prevent the penetration of liquid fuel into the activated carbon filter, to permit the seal to be checked by applying a partial vacuum and to provide a filler head which can be manufactured inexpensively, an insertion body (22) is provided which forms a funnel (23) which is adjoined by a neck (24) which accommodates the fuel nozzle, which insertion body (22) has, in addition to the neck (24), two vertical blind holes (31, 32), open at the bottom, and a transverse duct (33) which connects the latter, wherein the first blind hole (31) is connected to the recirculating line (10), and a float (40), which clears or closes off the connection to the transverse duct (33), is guided in the second blind hole (32).

Abstract: A fuel reservoir for a motor vehicle, including a shell body that is provided with inlet and discharge openings and is manufactured in a synthetic material. The shell body has a storage chamber which receives fuel, and a reinforcement which receives stress forces acting on the shell body is provided inside the storage chamber.

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: 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 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.
