Definitions

  • the invention initially relates to a fuel pump device for a fuel system of an internal combustion engine, in particular with direct injection, with a fuel pump and a drive motor connected thereto.
  • Such a fuel pump device known from EP 0 725 212 A2.
  • a fuel system in which a first fuel pump device promotes fuel from a fuel tank to a second fuel pumping device and from there via a high-pressure region to injectors.
  • Both fuel pumping devices each comprise a fuel pump and an electric drive motor connected to the fuel pump.
  • the delivery rate of both fuel pumping devices can be changed and adjusted via the rotational speed of the electric drive motor.
  • the non-prepublished DE 101 11 837 A1 discloses an axial piston pump and an electric drive motor, which are housed in an outwardly sealed housing.
  • the disadvantage of the known fuel pumping device is that its handling and integration into the fuel system is difficult and therefore makes the structure of the fuel system expensive. Also, the pump power does not correspond to the operating points of the Internal combustion engine meets the requirements.
  • the design of the fuel pump as a radial piston pump allows the generation of high pressures, as required in modern fuel systems for internal combustion engines with gasoline direct injection.
  • the unit consisting of the drive motor and the fuel pump can be preassembled, so that in the construction of the fuel system, for example in a motor vehicle, only one common part and not two separate parts are to be handled.
  • the accommodation of the drive motor and the fuel pump in a common fluid-tight housing further improves the handling of the thus designed fuel pump device.
  • a fluid-tight housing is already required for the fuel pump so that this does not or hardly leads to additional costs.
  • the drive motor in the fluid-tight housing it is ensured that the drive motor is protected against contamination from the outside.
  • less pollution-tolerant, but powerful electric motors can be used, which once again benefits the performance of the fuel pumping device.
  • the service life of the fuel pump device is improved by this measure.
  • the efficiency of the fuel pump device according to the invention is also improved by the fact that the otherwise required shaft seal can be omitted from the fuel pump to the drive motor.
  • Such a shaft seal is always associated with some friction and leakage, both of which reduce the efficiency of the fuel pump.
  • the omission of the shaft seal also reduces costs.
  • the fuel pump comprises a drive shaft with at least one bearing, which is at the same time a rotor shaft of the drive motor.
  • a designed fuel pump device is very compact, since it is dispensed with separate waves on the one hand for the fuel pump and on the other hand for the drive motor. Also, less bearings are required for storage of the drive shaft or the rotor shaft, resulting in smaller dimensions and lower production costs of the fuel pump device.
  • the interior of the housing of the unit formed by the fuel pump and the drive motor is flowed through by the fuel at least in the region of the drive motor.
  • the flow guide is formed in the interior of the housing of the unit formed from the fuel pump and the drive motor so that the fuel first flows through the drive motor at least partially and then passes to the fuel pump, and that in the flow path between the drive motor and fuel pump, a filter device , in particular a sieve, is present.
  • the drive motor is optimally cooled, which has an advantageous effect on its efficiency and what overall improves the delivery rate of the fuel pump device. This prevents blockages in the flow channels of the fuel pump or at their valve devices. These could be caused by parts which detach, for example, from the magnets of the drive motor made of a brittle material. In this development of the fuel pump device according to the invention, the high efficiency is thus present over the entire service life of the device.
  • the drive shaft of the fuel pump has an Exzenderabrough and arranged around the Exzenderabrough around cam ring and for each piston connected to the piston and the cam ring abutting slide, wherein in the radially outer peripheral surface of the cam ring circumferential groove and in the shoe and in the piston, a radially extending channel are present.
  • the groove and the channels can be introduced in a simple and inexpensive manner. Through the groove and the channels of the fuel can be performed with less flow resistance. The introduction of complex holes, for example, in a cylinder head of the radial piston pump thus eliminated. As a result, the costs are additionally kept low.
  • valve element of the suction valve is made of a ceramic material.
  • a ceramic valve element builds relatively easily, which has advantages in terms of valve dynamics. Further, such a valve element is insensitive to wear, so that the life of the thus configured fuel pumping device is high.
  • this comprises an electronic control part, which controls the drive motor, with a control part housing which on the housing of the fuel pump and the drive motor formed unit is attached with at least one fastening means.
  • An electronic control is required for most types of drive motors anyway to provide the required signals for the drive in the desired manner.
  • the fact that the electronics are housed in a separate control part it can be optimally pre-assembled. In particular, in the pre-assembly such mounting conditions can be met, which are required for the correct functioning of the control electronics. Subsequently, the control part housing of the control part can be fixed to the housing of the unit formed by the fuel pump and the drive motor. If this occurs before the engine is mounted on it, the assembly work on the internal combustion engine is simplified.
  • the fastening means to penetrate the wall of the housing of the unit formed by the fuel pump and the drive motor, and for the fastening means to be sealed off from the housing of the unit formed by the fuel pump and the drive motor by a sealing means.
  • the fastening means penetrates the wall of the housing of the unit formed from the fuel pump and the drive motor, a particularly secure and stable attachment of the control part housing is made possible.
  • the sealing means provided according to the invention ensures that fuel which is present in the housing can not escape from it to the control part.
  • a degassing channel leads to the outside. This ensures that, when fuel gases, which pass the sealant past or through it from the interior of the housing of the drive motor and the fuel pump to the outside, kept away from the sensitive control electronics and be discharged into the environment instead.
  • the assembly of the fuel pump device is further simplified in that the housing of the unit formed by the fuel pump and the drive motor comprises at least two parts which are fluid-tightly interconnected, wherein on the one hand the fuel pump and a rotor connected to the drive shaft and the other Part of the stator belongs. Both parts can thus be pre-assembled independently in possibly different production facilities. The final assembly is still very simple.
  • the invention also relates to a fuel system for a direct injection internal combustion engine having a first fuel pump which delivers fuel to a fuel pumping device comprising a second fuel pump and an electric drive motor connected thereto and a high pressure region into which the second fuel pump delivers and is connected to the at least one fuel injection device.
  • the second fuel pump is a radial piston pump and the drive motor and the second fuel pump unit with a common fluid-tight Form housing.
