Definitions

  • the invention relates to a fuel extraction device for arrangement in a fuel tank with a supply and a return line, a Fuel filter and receptacles for the supply and return line.
  • Fuel take-off devices are mainly used in fuel tanks diesel-fuel powered motor vehicles used.
  • the invention is based on the object, a fuel extraction device to create a good cold start, cost effective and easy to assemble.
  • the fuel extraction device comprises a flow line, a return line and one near the bottom of the fuel tank arranged fuel filter.
  • the up to the filter led forward and Return lines are arranged in receptacles.
  • the recording for the Return line is for splitting the fuel flow in at least two Partial flows formed.
  • a down and side closed area arranged to receive this recording that at least a partial flow of the Return line is directed in this area. In this area is the Recording the flow line arranged. Another partial flow is against led directly to the filter surface.
  • the advantage of this fuel extraction device is that of the Engine recirculated hot fuel, split into several sub-streams, wherein at least a partial flow is passed directly to the filter surface, so that paraffin particles accumulated there especially at cold temperatures dissolve and fuel at least over this portion of the filter surface can be sucked.
  • the fuel extraction device according to the invention thus has a very good cold start behavior. Furthermore, by the Arrangement of the return line inside the filter has a cleaning effect achieved by the filter, since the outside of the filter surface accumulated impurities be washed away. Furthermore, the down and ensures laterally closed area of the filter that always a certain amount of Fuel is fed to the supply line. The fuel extraction device thus requires no additional storage devices. As a result of the simpler Structure and the associated easier assembly is the invention Fuel extraction device extremely inexpensive.
  • the filter is cylindrical, wherein the filter surface is the lateral surface. Even at low level in the Fuel tank to ensure the supply of fuel, it is advantageous to arrange the filter surface up to a partial area of the floor. It is it is expedient that this sub-area corresponds to that filter area to which the coming from the return and directed to the filter surface partial flow impinges.
  • the downwardly and laterally closed region is in an advantageous embodiment from the bottom of the filter and vertically arranged vanes educated.
  • these guide elements arranged as a wall on the lateral surface of the filter, with this wall extending from the bottom over a partial circumference of the lateral surface.
  • This training will be a particularly large volume of fuel for the Supply line provided.
  • By guiding elements in this area can be the Increase distance from the return line to the flow line. Consequently there is a better mixing of the originating from the return Fuel with the fuel in the fuel tank. simultaneously can thus gas bubbles from the partial flow of the return without additional Separate effort.
  • the pictures consist of several guide elements. Especially advantageous is the training of recordings with at least three guiding elements, the are arranged to each other such that the supply and return line each center between the guide elements.
  • the structure of the filter simplifies when the intake of the supply line has a designed as a dome guide on which the flow line centered. Such a dome can also accommodate the return line form when formed on the circumference of the return line guide elements for Guiding the partial flows are arranged.
  • the partial streams can be generated particularly easily when recording the return line has a further guide element, which in the return line is arranged.
  • the return flow can be divided into two partial streams.
  • the filter is particularly easy if it is made of plastic in one piece Injection molding is made.
  • the Floor with the shots and the guide elements as a separate component in the Filter clipped. By molded locking elements, the assembly of the filter further simplified.
  • the fuel extraction device 1 shown in Figure 1 is inserted by means of a flange 2 in an opening 3 of a fuel tank 4.
  • a flow line and a return line 5 are connected, wherein the flow line is disposed behind the return line 5.
  • a profile 7 is arranged, in which the supply and return line 5 and a non-illustrated level sensor are arranged.
  • This profile is followed by a filter 8 made of POM, which is shown in a partial section along the line BB in FIG.
  • the fuel extraction device 1 extends in the manner in the fuel tank 4, that the filter 8 of the fuel extraction device 1 is disposed in the vicinity of the fuel tank bottom 9.
  • the lateral surface 10 of the filter 8 has a grid structure which forms the filter surface 11 and flows through the fuel from the fuel tank 4 into the filter 8.
  • the mesh size of the filter surface 11 is 0.6 mm.
  • Down the filter 8 is closed by a bottom 12.
  • the return line 5 is guided into the filter 8.
  • the receptacle 13 has guide elements 14-14.3, between which the return line 5 is centered.
  • Another guide element 17 of the receptacle 13 is arranged as a vertical wall centrally to the guide elements 14, 14.1 and within the return line 5. The guide element 17 causes the splitting of the return into two partial streams.
  • the guide element 17 and the guide elements 14, 14.1 direct the lying in the plane of sub-stream T 1 on the side to the bottom 12 formed filter surface 11.
  • the opposite region 18 is closed by the guide elements 14, 14.1 the bottom 12 and a arranged in the lateral surface 10 wall 19 down and laterally.
  • latching elements 20 are further arranged for fixing a filling level sensor, not shown.
  • the level sensor is guided.
  • recesses 22 are formed on the filter 8, engage in the locking elements 23 of an intermediate piece 24 of the fuel extraction device 1.
  • the cut along the line AA of Figure 1 filter 8 is shown in Figure 2.
  • the flow line 6 and the return line 5 are arranged in receptacles 13, 15.
  • the receptacle 13 of the return line 5 consists of the guide elements 14 - 14.3.
  • the formed on the receptacle 13 guide member 17 divides the fuel of the return line 5 in the partial flows T 1 , T second
  • the guide element 17 and the bottom 12 of the partial flow T 1 is directed onto the filter surface 11, which extends over a range of 90 ° of the lateral surface 10 to the bottom 12 of the filter 8.
  • the partial flow T 2 flows into the region 18, which is bounded by the bottom 12, the guide elements 14.1, 14.3, the in the lateral surface 10 over a range of 270 ° extending wall 19 and the guide element 25 down and laterally.
  • the receptacle 15 further has support surfaces 26 on which the supply line 6 is supported at a distance of 3 mm from the bottom 12. This ensures that fuel from the region 18 can flow into the flow line 6.
