Definitions

  • the invention relates to a delivery unit for conveying fuel from a fuel tank to an internal combustion engine of a motor vehicle with a fuel pump, which is arranged in a swirl pot, with a fuel filter, which is arranged downstream of the fuel pump and arranged in the swirl pot pressure control valve.
  • Valves have the task to keep the pressure in the supply line with the fuel pump switched off in order to promote fuel at a subsequent start in the shortest possible time fuel with nominal pressure via the feed line to the engine of the motor vehicle.
  • the problem arises that the hot fuel cools when the motor vehicle is at a standstill and as a result reduces its volume. This leads to a negative pressure in the fuel-carrying lines and units. It may happen that the vacuum opens the valve and air in fuel-carrying
  • the present invention is therefore an object of the invention to provide a conveyor unit, which is to produce with little effort.
  • the object is achieved in that the valve is arranged downstream of the fuel filter and in a constantly filled with fuel area of the swirl pot. Due to the constant immersion of the valve in the fuel is sucked when opening the valve due to a negative pressure in the fuel-carrying lines fuel. This prevents the ingress of air into the fuel-carrying lines. When restarting the internal combustion engine therefore no disturbing air cushion must be filled, whereby the delivery unit promotes fuel in a shorter time fuel with nominal pressure to the engine.
  • the arrangement of the valve in a constantly filled with fuel area of the swirl pot is ensured by the fact that the valve is arranged in the bottom region of the swirl pot.
  • the fuel line outgoing flow line often begins in the upper region of the swirl pot, but the valve must be located in the bottom region of the swirl pot, in another embodiment, the flow line in the region of the valve in the bottom region of the swirl pot.
  • Such a routing of the flow line is avoided according to another embodiment, characterized in that in the flow line or in the outlet of the fuel filter, a branching off of the feed line connecting line is arranged, and that this connection line is connected to the valve.
  • connection line is mounted in a holder arranged on the filter housing.
  • the holder is particularly easy to produce by being integrally molded onto the filter housing.
  • connection line is a rigid line.
  • the mounting of the delivery unit is simplified if the connection line is formed integrally with the valve housing.
  • Injection molding in particular, has proved to be a particularly cost-effective process for large-scale injection molding
  • the valve can be a pressure control valve.
  • Figure 1 a schematic representation of the delivery unit in a fuel tank
  • Figure 2 a perspective view of the filter housing with the valve.
  • FIG. 1 shows a fuel tank 1 of a motor vehicle not shown with a conveyor unit 2, which is inserted through an opening 3 in the fuel tank 1. After installation, the opening 3 is closed with a flange 4.
  • the delivery unit 2 consists of a prestressed against the bottom of the fuel tank 1 swirl pot 5.
  • a fuel pump 6 is arranged, which sucks fuel from the swirl pot 5 and promotes via an outlet 7.
  • a fuel filter 8 is arranged, which, viewed fluidly, is arranged downstream of the fuel pump 6, so that the fuel pumped by the fuel pump 6 reaches the fuel filter 8 via an inlet port 9.
  • the filtered fuel then passes through a feed line 10 through the flange 4 to an internal combustion engine, not shown, of the motor vehicle.
  • the housing 11 of the fuel filter 8 has a one-piece molded web 12, which merges into a pump holder 13. In the pump holder 13, the fuel pump 6 is mounted.
  • the filter housing 11 is made of polyoxymethylene.
  • From the flow line 10 is a connecting line 14, which extends to a valve 15 in the bottom region of the swirl pot 5.
  • Figure 2 shows the filter housing 11 with the outlet port 16 and the inlet port 9. The fuel filter is not shown in this view.
  • To the filter housing 11 of the pump holder 13 is integrally formed by injection molding, so that both components form a unit.
  • the outlet 16 is formed as a T-piece, to which the flow line 10, not shown, and the connecting line 14 are connected.
  • connection line 14 is formed as a rigid line, which is mounted in addition to increasing the stability and against unwanted movements in a holder 17, wherein the holder 17 is molded onto the filter housing 11.
  • the valve 15 adjoins the lower end of the connecting line 14, the housing 18 of which is formed integrally with the connecting line 14.
  • the L-shaped connecting line 14 is additionally reinforced in the angled region by a molded web 19.
