Definitions
- the invention relates to a device for delivering fuel to one Internal combustion engine with the features mentioned in the preamble of the main claim.
- a generic device for is known from the document DE 195 13 822 A1 Conveying fuel from a fuel tank to an internal combustion engine Motor vehicle.
- the facility consists essentially of a Internal combustion powered feed pump, which is designed as a gear pump and is connected to the fuel tank via a delivery line. This Gear pump delivers the fuel to the injection system of the internal combustion engine.
- the feed pump forms an assembly together with an air-conveying pump, whose suction side to generate a negative pressure with a brake booster Motor vehicle is connected.
- the fuel supply is also previously known from document DE 196 12 605 A1 an internal combustion engine by means of a fuel-flushed and in the fuel tank to accommodate housed electric motor-driven feed pump.
- the feed pump is located in a storage pot also arranged in the fuel tank Operatively connected. In the lower area of this storage pot there is a separate one Liquid jet pump, via which the storage pot is filled and regulated becomes.
- a second additional pump is provided for the fuel supply described above Securing funding after the fuel tank runs empty is necessary, too deviates from the usual pump types in motor vehicle construction.
- the invention has for its object a generic feed pump in terms improve their suction behavior after emptying the fuel tank while doing so to achieve self-venting.
- the object of the invention is achieved by the in the characterizing part of Features mentioned claims.
- the advantages of the invention are in the optimal design of the pump unit with a pressure side Storage pot. Even after the fuel tank is empty, it is quick Fuel delivery with simultaneous ventilation, so a quick engine start is possible.
- the features of the subclaims are related to the description their effects explained.
- Fig. 1 are essential parts of the fuel supply of an internal combustion engine shown schematically.
- a feed pump 1 driven by the internal combustion engine sucks fuel from a fuel tank 5 and first fills a storage pot 3 which vented at the same time.
- a check valve 7 Located in the suction line 6 of the feed pump 1 a check valve 7 opening in the direction of the fuel pump 1, it prevents this Sucked fuel falls back into the fuel tank 5.
- One or more fuel pressure lines 2a are above the feed pump 1 Storage pot 3 connected (Fig. 2 and 3), they feed an injection pump or Pump-nozzle elements with fuel (both not shown). Not the one Internal combustion engine from the injection pump or the pump-nozzle elements supplied fuel flows through a return line 8 and a pre-pressure valve 9 in the Fuel tank 5 back.
- the storage pot 3 axially covers the area of the feed pump 1 and part of the adjacent sealing limits (Fig. 2 and 3).
- the ones that form the sealing limits, for example seals 10 consisting of round rings are located in the area of the storage pot 3 in constant contact with fuel over a large part of its extent.
- A is preferably at the highest point of the storage pot 3 Pressure relief valve 11 connected. This pressure relief valve 11 opens at higher pressure than the pre-pressure valve 9. The return of fuel takes place via the Pressure relief valve 11 and a return line 12 to the suction side of the feed pump 1.
