Definitions

  • the invention relates to a fuel supply system according to the preamble of claim 1.
  • a fuel supply system of an internal combustion engine usually comprises a plurality of units.
  • a fuel pump delivers fuel from a fuel supply from a fuel tank via various units until the fuel finally enters a combustion chamber of the internal combustion engine.
  • One of the units is for example a pressure regulator, a fuel accumulator, a pressure damper, a fuel filter or a fuel injection valve.
  • one of the units for example, the pressure regulator, itself or a component of this unit, is electrically conductive, but the electrically conductive member or the unit is arranged electrically isolated, for example, characterized in that the unit on a non-conductive Plastic existing body is arranged.

  • an electrostatic charge of the electrically conductive component In the aggregate with an electrically conductive component can be carried out by electrical charge separation, an electrostatic charge of the electrically conductive component. Since the electrostatic charging of the electrically conductive component usually does not cause any problems, in particular no malfunction, the electrostatic charging of the electrically conductive component is normally unnoticed or at least ignored. Because there are aggregates through which the fuel flows through a narrow gap, for example at a high flow rate, for example in a pressure regulator, the electrostatic charge of the electrically conductive component can be very strong.
  • EP-A-0 754 852 shows a tank pump assembly having a fuel pump and a fuel filter.

  • the fuel filter must be prepared accordingly, which is why the fuel filter must have a special housing.
  • the pole piece must be adjusted accordingly.
  • US 3,289,200 shows a housing for a control light. At the existing plastic housing two pins are integrally formed. On the pins electrical connectors are attached. Between the pins and the electrical connecting elements, the connecting wires of a control bulb are clamped.
  • the fuel supply system according to the invention with the features of claim 1 has the advantage that an electrostatic charge of the electrically conductive member is prevented and any source of danger caused thereby is eliminated, being achieved with the clamping spring in a very simple manner that one with the electrical potential connecting electrical connection can be very safe and reliable connected to the electrically conductive component. Frequently, no change or redesign of the electrically conductive component is required.
  • FIGS. 1 to 5 show different exemplary embodiments or differently executed details.
  • the inventively designed fuel supply system is used for supplying fuel in an internal combustion engine.
  • an internal combustion engine for example, a gasoline engine come into question.
  • the fuel is, for example, gasoline or diesel, wherein, because gasoline is particularly easily flammable, it is proposed to carry out the fuel supply system according to the invention at least when the fuel is gasoline.

  • Within the lid. 6 There is a channel 24 and a return channel 26.
  • the channel 24 has an inlet side 24a and a secondary side 24b.
  • the first housing part 11 has a bottom portion with a central recess 27 on the side offset the bottom portion of the housing part 11 has a passage 28.
  • On the cover 6 a protruding through the central recess 27 nozzle is formed.
  • a valve seat 29 is provided at one of the closing body 18 of the membrane unit 14 facing the front end of the neck of the plastic cover 6, a valve seat 29 is provided.

It may also be that the lid 6 is made of electrically conductive material, but for example by an electrically non-conductive intermediate plate, the lid 6 is electrically isolated from other electrically conductive components of the motor vehicle. This results in an electrically insulating body 30, which is formed in the illustrated embodiment in the form of the lid 6.
  • a provided in the interior of the fuel tank 2 fuel pump 32 sucks fuel from an existing in the fuel tank 2 fuel supply 34 and delivers the fuel through a pressure line 36 via the inlet side 24a in the channel 24.

  • the fuel flows through the plastic cover 6 or electrically insulating body 30, then this can lead to a charge separation and thus to an electrostatic charge, for example, of the housing 10.

  • the electrostatic charge of the housing 10 has reached a critical value, for example a few 1000 V (several thousand volts), then it can happen that an electrical flashover occurs in which the electrostatic charge is partially or completely degraded.
  • the housing 10 is made of metal and thus is a good electrically conductive component, the charge built up on the entire housing 10 discharges in a concentrated manner in a short time, because the charge of the entire housing 10 flows in place of the flashover. As a result, the risk is not excluded that the electrical flashover reaches a size that leads to ignition of a fuel-air mixture. A certain ignitable mixture inside or outside of the fuel tank 2 in the area of the fuel supply system can not always be completely avoided.

Depending on requirements, the positive pole or the negative pole can be connected to the electrical ground of the motor vehicle.
