  • the high pressure area also includes a high pressure pump through which fuel is delivered to the high pressure accumulator.
  • the fuel injection device also has a low-pressure region which is connected at least indirectly to a fuel reservoir.

  • a low pressure pump In the supply connection can be arranged a low pressure pump, is conveyed by the fuel from the fuel tank to the suction side of the high-pressure pump.
  • the high pressure area is separated from the low pressure area to prevent leakage of fuel.
  • the fuel is heated, in particular in the high-pressure region of the fuel injection device.
  • the fuel cools in the high pressure region, wherein the volume is reduced, which can lead to the formation of vapor bubbles in the high pressure region.
  • the subsequent restart of the internal combustion engine is made more difficult, since first the vapor bubbles must be displaced in the high pressure region before fuel injection and thus combustion in the internal combustion engine can begin.
  • the fuel injection device according to the invention with the features of claim 1 has the advantage that a vapor bubble formation is avoided when cooling the fuel in the high pressure region, since fuel can flow from the low pressure region in the high pressure region to compensate for the reduction in volume and thus safe starting of the engine is possible.
