Abstract: A fuel delivery unit of a motor vehicle comprises a prefilter arranged inside a swirl pot, said prefilter having a filter element, and at least one connection piece for connecting a supplementary filter element. The at least one connection piece, in its initial condition, is closed, and is opened when the supplementary filter element is attached. The invention allows the fuel delivery unit to be adapted to projected filter surfaces of the prefilter.

Abstract: A device for collecting fuel in a fuel tank of a motor vehicle having a prefilter arranged inside a swirl pot. The prefilter has a section rising from a horizontal plane and a section lying in the horizontal plane. The sections of the prefilter are produced as one piece and are connected to the swirl pot. The prefilter has an especially large surface.

Abstract: A fuel delivery unit for a motor vehicle, wherein a swirl pot has a base formed from an upper part and a lower part, and an outer wall connected to the base, forming a seal. The upper part and the lower part bound fuel-delivering regions of a suction jet pump and of a section of a feed line. This arrangement allows the fuel delivery unit to be produced at particularly low cost.

Abstract: A delivery unit for delivering fuel in a fuel tank comprises a prefilter and swirl pot which are produced as one piece. The prefilter is produced during die-casting of the swirl pot. The invention allows the delivery unit to be produced in an especially inexpensive manner.

Abstract: A feed unit for feeding fuel has a housing formed integrally with the casing of a swirl pot, the housing comprising a fine filter. The fine filter is configured open toward one side and is closed by a cover. The cover is formed integrally with a base plate sealing the casing of the swirl pot. As a result, the feed unit has a particularly low number of components to be assembled and can be produced in a particularly cost-effective way.

Abstract: A pump device for feeding fuel in a fuel tank of a motor vehicle, having a suction jet pump and having a control valve for regulating the feed rate of the suction jet pump, A valve body can be moved counter to the flow direction of a fuel jet of the suction jet pump to throttle the feed rate. In this way, forces for opening the control valve are kept low. A float controls the valve body via a shaft which is guided through a mixing tube of the suction jet pump.

Abstract: A suction jet pump with a propulsion jet nozzle, a mixing tube, a suction port and a suction line attached thereto, wherein at least part of the mixing tube is arranged in a pot. The suction jet pump is used to supply fuel in a fuel container or from a fuel container in a swirl pot that is arranged inside the fuel container.

Abstract: A feed unit has a surge chamber 1, a fuel pump 2, which is arranged in the surge chamber 1, and a pump holder 3, the fuel pump 2 being arranged in the pump holder 3 and the pump holder 3 being fastened in the surge chamber 1. The pump holder 3 has at least two rods 6 which are fastened in the surge chamber 1, the rods 6 being connected to a mount 5 for the fuel pump 2.

Abstract: In a feed unit for feeding fuel from a fuel container of a motor vehicle a surge part (1) has a base plate (9) and an adjoining tubular section (10). The base plate (9) is fabricated in one piece with a nozzle (15) and a mixer pipe (16) of a suction jet pump (8) and has receptacles (21, 13) for a fine filter (3) and for supporting rods (22) of a fuel pump (2). The feed unit is of particularly simple design as a result of this and can be fabricated in a cost-effective way.

Abstract: A coupling valve structure 26 is provided for a fuel supply module 20. The module has a fuel pump 20 disposed in a fuel reservoir 18, a feed line 21 in fluid communication with an outlet of the fuel pump for feeding fuel to a high pressure pump 16 and thus to an engine, and a return line 22 for returning excess fuel from the engine or high pressure fuel pump to the reservoir 18. The coupling valve structure 26 includes a check valve 28 constructed and arranged to communicate with the feed line to permit fuel to be delivered to the engine and to prevent the fuel from draining back to the fuel pump, and a pressure relief valve 30 integrally connected with the check valve via a conduit 23.

Abstract: A fuel supply system for a motor vehicle has two feed units arranged in a fuel tank. The feed units in each case feed fuel out of baffles to an internal combustion engine of the motor vehicle and to suction jet pumps. This ensures a reliable supply of fuel to the internal combustion engine, even in the case of a very high fuel requirement and in the case of an angled design of the fuel tank.
