Abstract: A device for delivering fuel has a fuel delivery unit placed inside a fuel tank and which consists of a swirl pot with a fuel pump situated therein for delivering fuel out via a flow line to an internal combustion engine, and with a ventilation system located inside the fuel tank and serves to withdraw fuel vapors from the fuel tank. This ventilation system consists of ventilation lines and a liquid trap for precipitating fuel. The ventilation lines are arranged with one end in the upper area of the fuel tank, and, with the other end, lead into the liquid trap. An activated charcoal filter located downstream from the liquid trap has a connection to the atmosphere. The liquid trap and the activated charcoal filter are situated next and at the height of the swirl pot. At least the liquid trap is mechanically connected to the swirl pot.

Abstract: The invention relates to a fuel supply device (2) for a motor vehicle, which comprises a fuel tank (1). An intake connection (24) of a fuel pump (7) is located in a ventilation device (4). The fuel pump (7) simultaneously takes in fuel from the fuel tank (1) and from the ventilation device (4). For this purpose, the fuel pump (7) and a bubble removal container (8) of the ventilation device (4) are configured as a single structural unit.

Abstract: A ventilation device (1) for a fuel container (2) with a liquid trap (3) and a suction jet pump (8) which is provided for emptying the liquid trap (3) has a filling-level limit switch (11) for detecting the filling level of fuel in the liquid trap (3). A valve (10) which is connected to the filling-level limit switch (11) is connected upstream of the suction jet pump (8). The suction jet pump (8) is first activated by means of the valve (10) when the intended filling level of fuel in the liquid trap (3) is exceeded.

Abstract: In a fuel tank (1), a condensate collector (13) of a venting line (12) with a closure lid (6) forms one structural unit. The closure lid (6) closes off an opening (7) in a wall (8) in the fuel tank (1). The condensate collector (13) has spring elements (17) for prestressing elastic venting lines (15) against the inside of the fuel tank (1) and the venting device (12) can be mounted through the opening (7) in the fuel tank (1).

Abstract: A fuel tank (1) has a constructional unit which can be preassembled and comprises a surge chamber (3) and venting device (6). The constructional unit is fastened to the bottom of the fuel tank (1) and has spring arms for prestressing openings (12, 13), which are provided for venting the fuel tank (1), against the upper wall of the fuel tank (1). The fuel tank (1) can be fitted in a particularly simple manner.

Abstract: The invention relates to a fuel tank (1) for a motor vehicle, the upper section of which is provided with at least one opening (4) of a ventilation system. According to the invention, at least one chamber (5, 6) for receiving fuel (2) when the fuel tank (1) is in an inclined position, is configured in the upper section (8) of the fuel tank (1).

Abstract: In a venting device for a fuel tank (1), a venting line (5) has a movable section (6) and a spring element (14). The free end of the venting line (5) is prestressed against an upper wall of the fuel tank (1). This ensures that a valve (7) which is arranged at the free end of the venting line (5) is always arranged in the vicinity of the upper wall of the fuel tank (1).

Abstract: The invention relates to a closure device for a fuel tank in a motor vehicle. The closure device has a filling-level transmitter and a blocking element which both together form a constructional unit. The blocking element is adjustable so that is it movable to a position in which the blocking element closes an opening in the tank.

Abstract: A plug neck for a filler neck of a motor vehicle has exchanging means for refueling-venting adaptation to different refueling devices. In the case of a refueling device which removes gases from a refueling channel by suction, a compensation chamber is connected permanently to the refueling channel via a connecting channel. For adaptation to a refueling device without suction removal, the connecting channel is closed and the vent valve is provided with a cap which has a connection neck for a line leading to an activated carbon filter. This allows tool costs for producing the plug neck to be kept particularly low.

Abstract: A pressure-limiting valve has a closure member (5) which, in its closed position, rests with initial stress against a valve seat (4) and has, on the side towards the valve seat (4), a shoulder (6) which can be formed by a circumferential flange (7) on the closure member (5). This induces enlargement of the opening stroke upon a slight opening of the closure member (5) as the flow strikes against the shoulder (6).

Abstract: A holding flange (5) is detachably connected on its bottom to a coupling part (7) within a fuel chamber (2). A flexible hose (8) leading to a sucking-jet pump (9) and a spring action arm (10) for holding the sucking-jet pump (9) down on the bottom of the fuel chamber (2) are fastened to said coupling part (7). For mounting and removal, the coupling part (7) can be separated from the holding flange (5) together with the structural parts fastened to it.
