The separate assembly of pre-filter and throttle in the treble line is complicated and expensive.
  • the DE 195 04 217 A1 shows a device for conveying fuel with a flow-fed Treb effet, which has a throttle for restricting the flow. Dirt particles from the fuel and the device can clog the throttle and thereby cause the vehicle to stall.
  • a device for conveying fuel is in US 6,474,310 given.
  • the device according to the invention with the characterizing features of the main claim has the advantage that the manufacturing cost can be reduced and the assembly of the prefilter and the throttle in the treble line is simplified by the throttle is integrally connected to a pre-filter.
  • the throttle has a throttle opening with an area that results in a circular design of a diameter of 0.6 to 1 millimeter, and the prefilter filter openings, wherein the area of a filter opening is smaller than the area of the throttle opening. This ensures that all dirt particles that could clog the throttle opening are filtered out upstream of the throttle opening.
  • the prefilter is designed as a filter pot with a filter bottom and a peripheral wall, wherein filter openings are provided in the filter bottom and / or in the peripheral wall, since in this way the largest possible filter surface is achieved, which is not susceptible to clogging.
  • the throttle is designed as a cover in which a throttle opening is provided, as this represents a particularly simple embodiment variant.
  • the filter cup and the cover are connected to one another via connecting webs, since the connecting webs provide a sufficient distance between the pre-filter and the throttle, so that both the fuel flowing over the filter bottom and the fuel flowing over the peripheral wall can flow to the throttle opening ,
  • FIG.1 shows in simplified form a device according to the invention for conveying fuel, Fig.2 on average, a throttle with integrated pre-filter and Fig. 3 a three-dimensional view of the embodiment according to Fig.2 ,
  • Fig.1 shows an inventive device for conveying fuel from a reservoir to an internal combustion engine of a motor vehicle.
  • the device according to the invention has a fuel delivery module 2 arranged in a storage container 1.
  • a fuel 3 is stored in the reservoir 1.
  • the fuel delivery module 2 consists of an example cup-shaped storage container 4, in which a feed pump 7 is arranged, the fuel sucks, for example via a filter 8 and a suction line 9 from the storage tank 4 and pressure increases via a pressure line 10 to an internal combustion engine 11 promotes.
  • the storage container 4 stores enough fuel to ensure that the fuel supply to the engine 11 is ensured by the feed pump 7, even if, for example, by cornering and consequent sloshing of the fuel in the reservoir 1, no fuel in the storage container 4 is promoted.
  • the storage container 4 is arranged with its bottom of the pot 5 near a tank bottom 6 of the reservoir 1.
  • the feed pump 7 is for example a flow pump, which is electrically driven by an actuator, for example an armature of an electric motor.
  • the filter 8 protects the device downstream of the filter 8 from coarse dirt particles contained in the fuel.
  • a check valve 14 and downstream of the check valve 14 a main filter 15 is arranged, which filters out the fine dirt particles contained in the fuel.
  • the check valve 14 prevents fuel with the delivery pump 7 is switched off from the pressure line 10 from downstream of the check valve 14 via the pressure line upstream of the check valve 14, the feed pump 7, the suction line 9 and the filter 8 back into the storage container 4. In this way, the pressure built up by the feed pump 7 in the pressure line 10 is maintained over a certain time even when the feed pump 7 is switched off.
  • a branch line 16 is provided on the pressure line 10, which opens into the storage container 4.
  • the branch line 16 has a pressure regulating valve 17.
  • the pressure regulating valve 17 opens and allows fuel to flow from the pressure line 10 via the branch line 16 into the storage container 4. In this way, the pressure in the pressure line 10 drops again below the predetermined pressure, so that the pressure control valve 17 closes and can no longer flow fuel through the branch line 16 into the storage tank 4.
  • the pressure in the pressure line 10 downstream of the check valve 14 is regulated to a constant value.
  • At least one suction jet pump 20, which conveys fuel from the storage container 1 into the storage container 4, is provided on the storage container 4.
  • a suction jet pump is for example from the DE 198 56 298 C1 the content of which is expressly intended to be part of the disclosure of this application.
  • a drive line 21 extends to a nozzle 22 of the suction jet pump 20th
  • a pre-filter 23 and downstream of the pre-filter 23, a throttle 24 is arranged.
  • the pre-filter 23 protects the throttle 24 from dirt particles that could clog the throttle 24.
  • the throttle 24 limits the volume flowing through the tapping line 21.
  • the throttle 24 is integrally connected to the prefilter 23. The prefilter 23 is thereby integrated into the throttle 24.
  • the nozzle 22 is arranged on an end of the haulage line 21 facing the storage container 1, for example clamped on or in the haulage line 21, clipped, glued or welded.
  • the nozzle 22 has a nozzle opening 28 opening into a suction chamber 27.
  • the suction chamber 27 is formed by a recess 25 in the bottom of the pot 5 and connected via a suction port 19 with the reservoir 1.

  • a suction jet pump with horizontally extending mixing channel is also referred to as horizontally arranged suction jet pump, a suction jet pump with vertically running mixing channel, however, referred to as standing arranged suction jet pump.
  • the mixing channel 29 opens at a the storage container 4 facing the end of the mixing channel 29 via another, closing in the direction of reservoir 1 check valve, for example, a shield valve 30, in the storage container 4.
  • the mixing channel 29 has at the end of the storage container 4 end, for example, a diffuser section 31st on, in which the mixing channel 29 extends in the flow direction, for example transversely to the plane of the drawing.
  • fuel is injected via the pressure line 10, the haulage line 21 and the nozzle opening 28 of the nozzle 22 as a propulsion jet into the suction chamber 27.
  • the propulsion jet entrains fuel in the flow direction upon entry into the suction chamber 27, so that a negative pressure is created in the suction chamber 27, which allows additional fuel to flow from the reservoir 1 into the suction chamber 27.
  • the fuel of the propulsion jet and the fuel entrained by the propulsion jet passes into the mixing vessel 29 via an inlet opening 37 of the mixing channel 29 and into the storage vessel 4 via a valve opening 35 of the umbrella valve 30.
  • Fig.2 shows on average the throttle with integrated pre-filter.
  • the arranged in the brake line 21 choke 24 is, for example, lid-shaped as a lid 40, wherein in the lid 40 a lid 40 penetrating the throttle opening 41 is provided.
  • the throttle opening 41 is arranged, for example, centric to the treble line 21 and has a diameter of 0.6 to 1 millimeter, for example, in a circular design, but can expressly have a different diameter and other shapes with different surface contents.

  • a clogged throttle 24 would cause no more fuel would be promoted by the ejector 20 into the storage tank 4, so that the level in the storage tank 4 would drop after some time and the feed pump 7 would not be supplied with sufficient fuel. Especially at low level in the reservoir 1, this would cause the vehicle to remain lying.
  • the throttle 24 with integrated pre-filter 23 is made as a separate component, in particular made of plastic, provided in the treble line 21.
  • the throttle opening 41 can be manufactured with high accuracy and without disturbing Trenngrate. Design changes for the adaptation of the flow line 21 flowing through the flow rate are therefore only required on the separate throttle 24 and not on the fuel delivery module 2 itself.
