Definitions

  • the invention relates to a conveyor unit for conveying
  • the delivery unit has a prefilter for filtering fuel flowing into the surge pot.
  • the force ⁇ fuel pump sucks the filtered fuel from the prefilter and promotes it via the fine filter to an internal combustion engine of the motor vehicle.
  • the fine filter is therefore exposed to the pressure generated by the fuel pump.
  • housing of the fine filter must therefore be designed pressure-resistant.
  • the housing of the fine filter is also madebil ⁇ det as separately attached to or in the fuel tank component.
  • the attachment of the housing of the fine filter is usually carried out by welding or Verklipsen with adjacent components of the conveyor unit.
  • the invention is based on the problem, a delivery unit of the type mentioned in such a way that it is particularly inexpensive to manufacture and is built as compact as possible ⁇ .
  • This problem is inventively solved in that a housing of the fine filter is made in one piece with a jacket of the swirl pot.
  • the inventive conveying ⁇ integrated on a particularly small number of components, since the housing of the fine filter and the casing of the swirl pot are ge ⁇ jointly manufactured and assembled. Therefore, a separate on ⁇ consuming manufacturing of the housing of the fine filter and its subsequent consuming assembly are avoided.
  • This enables the delivery unit of the invention can particularly kos ⁇ ready-effectively.
  • the fiction, modern ⁇ conveying unit designed particularly compactly by the arrangement of the housing of the fine filter to the wall of the swirl pot. The wall of the surge chamber thereby contributing to Stabili ⁇ ty of the housing of the fine filter.
  • the assembly of a filter cartridge in the fine filter is particularly simple according to an advantageous embodiment of the invention, when the housing of the fine filter is sealingly closed from one side of a lid.
  • the housing of the fine filter is open at the bottom and when the lid is made in one piece with a bottom plate of the baffle.
  • the housing of Feinfil- ters In contrast to the surge chamber, the housing of Feinfil- ters must have a high stability since it has to withstand the pressure generated by the power ⁇ fuel pump.
  • the housing of the fine filter has a high stability, when the housing of the fine filter is curved at its end facing away from the lid. To further increase the stability of the housing of the fine filter, it helps if the housing of the fine filter has stiffening webs on its outer side. Due to this design the housing of the fine filter and the casing of the surge chamber may be gefer ⁇ saturated with approximately the same wall thickness, resulting in a particularly simple manufacturing of plastic injection molding as this, the housing of the fine filter and the casing of the swirl pot in the Vin ⁇ sentlichen need the same cooling time.
  • the stiffening webs have the same wall thickness as the housing of the Feinfil ⁇ age .
  • the stiffening webs require the same cooling time as the housing of the fine filter.
  • the stiffening webs of the housing of the fine filter are arranged parallel to the wall of the swirl pot.
  • the unit can be made of housing of the fine filter and the Schwall ⁇ pot in an axially demoulding injection mold.
  • a telescopic guide for supporting the surge pot in the fuel tank is arranged on the housing of the fine filter. Due to this design, the telescopic guide leads to a stiffening of the housing of the fine filter. This reduces the number of stiffening for encryption of the housing of the fine filter provided auctioning ⁇ Fung webs can be kept particularly low.
  • further components of the delivery unit such as pump holder and derglei ⁇ chen are also arranged to increase the rigidity of the housing of the fine filter.
