Definitions

  • the invention relates to a fuel delivery unit with a swirl pot and a fuel pump fastened in the swirl pot, with a fuel filter and with a sealing connection of the fuel filter with the swirl pot and with the fuel pump.
  • the fuel filter arranged within the surge pot is usually designed as a fine filter and filters the fuel drawn in by a main stage.
  • a pre-filter arranged in the suction area of a preliminary stage of the fuel delivery unit is located outside the surge pot.
  • the pre-stage conveys fuel from the fuel tank through the pre-filter into the swirl pot.
  • the fuel filter is usually arranged in the central region of the swirl pot and has a housing through which the fuel flows axially with a filter element arranged therein.
  • a disadvantage of the known fuel delivery unit is that the filter effect is very limited by the filter element. The filter element can quickly become clogged with dirt particles, which leads to a severe impairment of the filter effect.
  • the invention is based on the problem of designing a fuel delivery unit of the type mentioned at the outset in such a way that it has a high filter action and a high dirt-holding capacity.
  • This problem is solved according to the invention in that a filter material almost completely fills a space between the swirl pot and the fuel pump.
  • This design means that the fuel filter has the largest possible dimensions, which leads to a particularly high filter effect. Dirt particles can settle in the filter material without directly leading to clogging of the fuel filter.
  • the fuel delivery unit according to the invention has a particularly high dirt holding capacity. Furthermore, this design largely suppresses noise from the fuel pump through the filter material.
  • connection of the filter material to the baffle requires particularly little effort if the filter material is integrally connected to the baffle.
  • a one-piece production of the filter material with the surge pot requires, according to another advantageous development of the invention, particularly little effort if the filter material is injected into the surge pot. This contributes to simplifying the assembly of the fuel delivery unit according to the invention.
  • noises of the fuel pump can be damped particularly easily if the filter material is designed as a damping material of the fuel pump.
  • the fuel pump can be easily retrofitted and replaced in the baffle if the filter material of the fuel filter has a recess for immediate Ren holder of the fuel pump has. Furthermore, the fuel delivery unit according to the invention therefore does not require a complex housing for fastening to the fuel pump, since the filter material can hold the fuel pump directly.
  • it further contributes to further simplifying the assembly of the fuel pump if the fuel pump has an interference fit in the recess of the filter material.
  • the filter material has a retention function for the fuel if the filter material has a sponge-like structure. This ensures that the filter material sucks up with fuel even when the fuel tank is almost empty. As a result, the fuel pump is reliably supplied with fuel even when the fuel tank is almost empty.
  • the filter material can be manufactured separately from the fuel pump and swirl pot with an outer diameter corresponding to the inside diameter of the swirl pot and subsequently inserted into the swirl pot.
  • the filter element can be mechanically reworked particularly easily and can be easily connected to other components by cast-on parts if the filter material is made of open-pored metal foam.
  • Metal foam is suitable, for example, magnesium foam or aluminum foam.
  • Such metal foams can be easily produced if a blowing agent is added to a molten metal and the mixture is introduced into a mold. The decomposition of the blowing agent usually releases hydrogen, so that a magnesium foam is formed that solidifies in the mold.
  • salt can be added to the melt and the salt can be washed out after the melt has solidified. As a result, small foam structures can be produced with little scatter in the material properties.
  • a low pressure loss when the filter material flows through can be easily achieved if the filter material is made of polymer foam.
  • So-called RGS polymers are particularly suitable as polymer foam.
  • Such a polymer foam is a fuel-resistant plastic that has a uniform porous structure.
  • the filter material has a high permeability to liquids and gases, good filtration properties and a high retention capacity for dirt particles.
  • the polymer foam can also be easily mechanically processed and used as a filter cartridge.
  • this shows a fuel delivery unit 2 according to the invention inserted in a fuel tank 1.
  • the fuel delivery unit 2 has a fuel pump 4 arranged in a swirl pot 3 with a prefilter 5 arranged in the bottom region of the swirl pot 3 and a fuel filter 6 which almost completely fills the space between the fuel pump 4 and the swirl pot 3.
  • the fuel pump 4 has a motor driven by an electric motor 7 Pump stage 8 with two impellers 9, 10 and a connecting piece 11 on its upper side.
  • a connecting pipe leading to an internal combustion engine (not shown) can be connected to the connecting piece 11.
  • fuel When driving the lower one of the impellers 9 of the pump stage 8, fuel is sucked out of the fuel tank 1 through the prefilter 5 and fed to the upper region of the swirl pot 3 via a riser pipe 12. Subsequently, the fuel flows through the fuel filter 6 to the upper one of the barrel veins 10. From there it is conveyed through the electric motor 7 to the connecting piece 11.
  • the flows of the fuel are marked with arrows in the drawing.
  • the fuel filter 6 has a filter material 13 concentrically surrounding the fuel pump 4.
  • a recess 14 for receiving the fuel pump 4 is arranged directly in the filter material 13.
  • the fuel pump 4 has an interference fit in the recess 14 of the filter material 13.
  • the filter material 13 is made in one piece with the baffle 3, for example by injection into the baffle 3. The filter material 13 almost completely fills the space between the baffle 3 and the fuel pump 4 and has damping properties for damping the noise of the fuel pump 4.
  • the filter material 13 with an outer diameter corresponding to the inner diameter of the swirl pot 3 and the recess 14 for the Fuel pump 4 manufactured and then inserted into the baffle 3.
