Abstract: A fuel pressure regulator and fuel filter assembly includes: a housing, having a connecting end having a fuel channel; a filter element, located in an accommodating cavity of the housing; a cover plate, located at a second end of the housing; a rear cover, having one end being an opening end and another end being a spring seat, and a sidewall, the opening end being connected to the housing; a spring, a first end thereof being pressed against the spring seat; a seal arranged in the rear cover, a second end of the spring being pressed against the seal; and a fixing ring that fixes the rear cover to the connecting end of the housing, the fixing ring being welded by laser to the connecting end. When fuel pressure is no greater than a spring preload, the seal closes the fuel channel.

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 corrugated pipe of a fuel line of a fuel supply system of a motor vehicle, with at least one flexible wavy portion having waves, the waves in each case having a wave crest and of a wave trough. The at least one wavy portion possesses at least one first region in which the waves have a larger diameter.

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 corrugated pipe of a fuel line of a fuel supply system of a motor vehicle, with at least one flexible wavy portion having waves. The waves are a wave crest and of a wave trough. The at least one wavy portion has a region, the cross section of which has a form deviating from the circular form.

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 device used to retain a fuel pump in a fuel container of a motor vehicle, which includes a pump holder that is made entirely of plastic by injection moulding. Retaining devices, which is used to join the pump holder to the fuel pump and to a baffle pot, are connected to each other by arms that are oriented away from each other. The arms, which are orientated away from each other, form a cardanic frame that dampens vibrations from the fuel pump.

Abstract: A fluid line for transporting fuel from a pump pre-filter to a fuel pump, which damps the noises of the fuel pump and a fuel delivery unit that is equipped with said fluid line Damping is achieved by at least one damping region, which is situated opposite the intake opening and which damps vibrations originating from the fuel pump.

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 fuel pump (9) with an adapter (12) there are provided latching means (16, 16?) disposed opposite one another and arranged at opposite ends of rocker elements (18, 18?) having a release mechanism (17, 17?) which can be actuated by hand. The rocker elements (18, 18?) are produced integrally with the adapter (12). By pressing together the release mechanism (17, 17?) the latching mechanism (16, 16?) are released from the fuel pump (9). The adapter (12) has a non-return valve (22) and/or a pressure-limiting valve (23). The fuel pump (9) can therefore be adapted to the particular application by simply exchanging the adapter (12).

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.
