  • Through the conveyor unit here only the amount of fuel promoted by the Internal combustion engine is consumed so that none Return flow from the internal combustion engine into the Storage container back is available.
  • Downstream of the Pressure sensor is a throttled flow, so that when operating the conveyor unit, a subset of the this delivered fuel is derived.
  • the delivery unit does not yet provide the internal combustion engine the full delivery rate, with a subset of the Conveyed fuel pumped by the throttled flow is derived, so under certain circumstances the amount of fuel supplied to the internal combustion engine is not is sufficient.
  • the fuel supply device with the features according to claim 1, in contrast, has the advantage that the throttled flow through the valve device only is opened when the fuel pressure is at least approximately has reached the predetermined target pressure, so that in particular at and after the start the whole of the conveyor unit delivered amount of fuel to the internal combustion engine becomes.
  • the valve device ensured that when the internal combustion engine is turned off throttled drain is closed and the fuel pressure in the injection system at least approximately on the predetermined target pressure is maintained. If it is at turned off internal combustion engine due to heating of the If the fuel comes to an increase in pressure, this can be relieved by the valve device.
  • Training according to claim 3 has the advantage that by the Pressure sensor the actual fuel pressure in the Injection system is detected, for example as a result contamination of the fuel filter may be less than the fuel pressure upstream of the fuel filter.

  • the check valve 22 opens in Delivery direction of the delivery unit 14 to the internal combustion engine 10 back and closes in the opposite direction, so that from the engine 10 no fuel in the Conveyor unit 14 can flow back.
  • a pressure relief valve 26 is also integrated, which is arranged upstream of the check valve 22.
  • the pressure relief valve 26 is at an opening pressure set, which is much higher than that usually and if the components of the Fuel supply device downstream of the Delivery unit 14 occurring fuel pressure. Provided by Disorders such as constipation or Kinking of lines, the fuel pressure rises sharply, so opens the pressure relief valve 26 and from Delivery unit 14 delivered fuel in the Flow back reservoir 12 so that damage the conveyor unit 14 or the line 30 is avoided.
  • the pressure relief valve 26 can for example be one Opening pressure between about 6 and 8 bar.
  • the conveyor unit 14 is preferably in one Storage container 28 arranged in the storage container 12 is inserted and opposite the reservoir 12 has much smaller volume.
  • the Storage container 28 is preferably by means of a Suction jet pump 29 fuel from the reservoir 12 promoted.
  • the reservoir 12 can be several from each other have separate chambers, fuel from or several chambers of the reservoir 12 into the chamber is promoted, in which the conveyor unit 14 is arranged.
  • a Fuel filter 32 Downstream of the Fuel filter 32 is a pressure sensor 34 in line 30 arranged through which the fuel pressure in line 30 downstream of the fuel filter 32 is detected.
  • the Pressure sensor 34 is electronic Control device 36 connected in which the signals of the Pressure sensor 34 in a manner explained in more detail below are processed.
  • the fuel pressure in is controlled by the control device 36 the line 30 evaluated and with a predetermined Target pressure compared.
  • the target pressure can be constant or depending, for example, on operating parameters of the Internal combustion engine to be variable.
  • the control device 36 also regulates the operation of the electric motor 16 of the Conveying unit 14 such that the 14th a quantity of fuel is pumped that is required around line 30 downstream of fuel filter 32 a fuel pressure detected by the pressure sensor 34 generate that is at least approximately equal to the predetermined Target pressure is.
  • the control device 36 preferably the voltage and / or power supply of the Electric motor 16 of the delivery unit 14 clocked, for what a Clock module 38 is provided.
  • the clock module 38 can the RMS value by varying the duty cycle the voltage applied to the electric motor 16 and / or the electric motor 16 supplied current can be changed, so that by the conveyor 14 to achieve the Required delivery pressure required volume is provided.
  • the frequency with which the electric motor 16 is clocked is preferably above an audible range of about 20kHz.
