Definitions

  • the invention relates to a fuel supply device for an internal combustion engine according to the preamble of patent claim 1.
  • fuel supply systems with a pump arrangement fed from a fuel tank, formed from the pre-feed and main feed pumps, is already known.
  • fuel delivery systems are known in a variety of embodiments, with the entire assembly consisting of the driving electric motor and multi-stage pump part often being accommodated in a common pot-shaped housing, namely the pump part and motor part arranged axially one after the other.
  • the rotatable pump parts can all sit on a common one, but it is also possible to arrange the rotatable pump part on a fixed axis by means of bearing bushings.
  • the main pressure stage designed as a positive displacement pump such as DE-PS 27 35 759
  • a flow stage which acts on the main stage with a slight admission pressure and thus prevents the usual drop in volume flow due to poor filling during hot delivery. Since the two pump stages are driven by a common shaft, there are delivery states in which the drive speed cannot be optimally adapted to the different pump stations. For example, the lowest possible speed for the positive displacement pump for noise reasons, while the flow pump only has favorable pumping properties at high speeds.
  • the object of the invention is to design a generic fuel supply device in such a way that the pumps can be operated independently of one another, the operation being to be achieved with the lowest drive power.
  • the new fuel supply device has the advantage that the drive speeds of the individual pumps can be optimally controlled by electronics acting from the outside on one of the two pumps or both pumps, as a result of which the noise level can be reduced while at the same time increasing the efficiency.
  • the option of completely stopping the pre-feed pump if necessary serves to reduce the power consumption from the vehicle electrical system and leads to an increase in service life.
  • FIG. 1 shows a fuel supply system, formed from a prefeed pump 1 and a main feed pump 2 for supplying fuel to an internal combustion engine 3, with electronics 4 being charged with engine parameters such as e.g. Speed, load etc. and other signals such as Fuel temperature and fuel pressure, forms a signal and thus controls and regulates the pre-feed pump.
  • engine parameters such as e.g. Speed, load etc.
  • other signals such as Fuel temperature and fuel pressure
  • both feed pumps 1, 2 with the associated drive rotors 5, 6 are accommodated in a common housing 7.
  • the drive rotor 6 of the main feed pump 2 is mounted on the extended shaft 11 of the drive rotor 5 of the pre-feed pump 1 by means of a hollow shaft 8, in which two bearings 9, 10 are arranged.
  • the shaft 11 of the drive rotor 5 of the prefeed pump 1 is supported at its two ends in two bearings 12, 13 in the housing.
  • the pre-feed pump 1 can also be arranged at one end and the main feed pump 2 at the other end of the housing.
