Definitions
- the invention relates to a device according to the preamble of the main claim. It is already known a device for conveying fuel from the US 5,080,077, with an arranged in a storage tank suction jet pump, which promotes fuel via a suction port in a bottom of the storage container from a reservoir into the storage container.
- the intake opening is preceded by a filter fabric which filters out the dirt contained in the fuel of the reservoir, so that they can not affect the functioning of downstream of the intake valves.
- the disadvantage is that the filter fabric increasingly clogged with heavily contaminated fuel and thus generates an increasing pressure loss, so that with the same power of the ejector increasingly less fuel in the
- the main claim has the advantage that in a simple manner, an alternative separation of the dirt particles from the fuel of the reservoir is provided by at and / or in the bottom of the storage container on one of the feed pump facing inside a plurality, to the storage container open towards the chambers Deposition of dirt particles contained in the fuel are provided, wherein the feed pump is arranged such that the fuel exiting from the feed pump flows over the chambers.
- chambers are arranged one behind the other in the flow direction of the fuel emerging from the feed pump, since in this way the particles are deposited particularly well in the chambers. It is also advantageous if, in addition, chambers are arranged side by side in the flow direction of the fuel exiting from the feed pump, since in this way the separation effect is even further improved.
- the chambers are formed by protruding from the bottom of the storage container walls, as this embodiment is particularly easy and inexpensive to produce by injection molding.
- Guide walls are formed, which are interconnected by a plurality of transverse to the flow direction separating walls, as this embodiment can be particularly simple and inexpensive to produce by injection molding.
- the storage container forms one of the guide walls, since in this way it is ensured that almost the entire fuel sucked from the storage container flows over the chambers and is cleaned of dirt particles.
- Guide walls and / or the dividing walls increases in the flow direction of the fuel exiting from the feed pump, since in this way the separation efficiency is improved.
- the delivery unit is a suction jet pump.
- the delivery unit is arranged such that the emerging from an outlet of the delivery unit in the storage tank fuel jet obliquely on a peripheral wall of the storage container, since the fuel jet is not divided in this way, but conforms to the peripheral wall and at this flows along. As a result, almost the entire amount of fuel sucked in flows over the chambers, so that sufficient cleaning of the sucked-in fuel is ensured.
- FIG. 1 shows a schematic view of the device according to the invention
- FIG. 2 shows a storage container with a delivery pump.
- Fig.l shows schematically a device for conveying fuel.
- the device is used for example for conveying fuel from a storage container 1 in a storage container 2 and from there via a delivery unit 3 to an internal combustion engine 4 of a motor vehicle.

- the delivery unit 3 sucks for example via a pre-filter 5 and a suction line
- the pre-filter 5 protects the device downstream of the prefilter 5 from coarse dirt particles contained in the fuel.
- a check valve 9 and downstream of the check valve 9 a main filter 10 is provided.
- the check valve 9 prevents fuel with switched-off delivery unit 3 from the pressure line 8 downstream of the check valve 9 after upstream of the check valve 9, by the delivery unit 3, the suction line 6 and the pre-filter 5 runs back into the storage container 2.
- the main filter 10 filters the - A -
- the fuel fine dirt particles contained in the fuel fine dirt particles and protects in this way, for example, the injectors of the engine from clogging.
- Downstream of the Hauptf ⁇ lters 10 branches off from the pressure line 8 from a pressure line 13, in which a pressure control valve 14 is provided.
- the pressure regulating valve 14 opens and allows fuel from the pressure line 8 to flow back into the storage container 2 via the overpressure line 13. In this way, the pressure in the pressure line 8 drops again below the predetermined pressure and the pressure control valve 14 closes again.
- a treble line 15 from, for example, serves to feed and drive a feed pump, for example, a so-called suction jet pump 16 with fuel from the pressure line 8.
- the suction jet pump 16 can also express fuel from the pressure line 13 or from a non-illustrated, from the
- the suction jet pump 16 promotes fuel from the reservoir 1 via a suction port 17 into the storage container 2.
- the sucked fuel is conveyed together with the so-called propulsion jet of the treble line 15 in the storage container 2.
- a throttle element 21 is provided in order to set and limit the volume flow flowing over the haulage line 15. So that the throttle element 21 can not clog, another pre-filter 22 is provided in the third brake line 15 upstream of the throttle element 21.
- An ejector pump is known, for example, from DE 198 56 298 C1, the content of which is expressly intended to be part of the disclosure of this application.
- the storage container 2 is for example pot-shaped with an axis 20 (FIG. 2) and has a bottom 23.
- the suction jet pump 16 is, for example, attached to the
- the fuel sucked in via the intake opening 17 is cleaned by filters of dirt particles. These filters increasingly clog so that the pressure loss of the filters increases and with the same power of the ejector increasingly less fuel is sucked into the storage container 2.
- this filter can be dispensed with by providing an alternative deposition of the dirt particles. In this way, the pressure loss in the region of the intake opening 17 remains constant, so that at the same power of the ejector 16 always the same amount of fuel is conveyed into the storage container 2.
- a plurality of chambers 24 for separating dirt particles contained in the fuel of the storage container 1 are provided on and / or in the bottom 23 of the storage container 2 on an inner side 19 facing the suction jet pump 16.
- the chambers 24 are formed on their bottom 23 remote from the top to the storage container 2 out.
- the shape of the chambers 24 is arbitrary.
- the suction jet pump 16 is arranged according to the invention such that the fuel exiting the suction jet pump 16 into the storage tank 2 flows over the chambers 24.
- the chambers 24 are arranged one behind the other in a flow direction 26 of the fuel emerging from the ejector 16 into the storage container 2. It can also be provided, in addition to arrange further chambers 24 in this flow direction 26 side by side.
- the chambers 24 are arranged, for example, part-ring shape behind one another, but can also be connected in a straight line or connected in any other form in series.
- the chambers 24 are formed for example by projecting from the bottom 23 of the storage container 2 walls 25. In another embodiment, the chambers 24 are formed for example by projecting from the bottom 23 of the storage container 2 walls 25. In another embodiment, the chambers 24 are formed for example by projecting from the bottom 23 of the storage container 2 walls 25.

In another embodiment, the chambers 24 are formed for example by projecting from the bottom 23 of the storage container 2 walls 25. In another embodiment, the chambers
- the guided from the suction jet pump 16 into the storage container 2 via the chambers 24 away fuel is slowed down by the chambers 24.
- the chambers 24 each represent a dead water area for the flow in which vortex form.
- dirt particles are deposited, for example by the slowing of the flow and the vortex formation in the chambers 24 due to their inertia and settle at the bottom of the individual chambers 24.
- the volume of the chambers 24 is designed such that there is a sufficiently large capacity for receiving dirt particles and the Do not completely fill chambers 24 within the average life of a vehicle.
- the capacity of the chambers 24 is significantly greater than the filtering solutions of the prior art.
- Fig. 2 shows a section of the device according to Fig.1, but in which only the
- the chambers 24 are formed by, for example, two spaced apart guide walls 28, between which a plurality of transverse to the flow direction 26 extending and spaced apart partition walls 30 are arranged, which connect the guide walls 28, for example.
