Definitions

  • the invention relates to a conveyor unit according to the type of the main claim.
  • a delivery unit on the market where all parts of the delivery pump are made of metal.
  • undesirable noises occur when the pump is rotating, which are caused, for example, by the metallic pump parts touching one another. These noises are particularly disturbing when the pump is used in a motor vehicle because it is amplified via the fuel tank and / or the vehicle body.
  • the conveyor unit according to the invention with the characterizing features of the main claim has the advantage that the unpleasant, undesirable noise is at least greatly reduced.
  • FIG. 1 shows the principle of a fuel delivery system of a motor vehicle, with a storage tank, a delivery unit shown partially and in section and with an internal combustion engine, in an unscaled representation
  • FIG. 2 shows a section through a delivery pump arranged in the delivery unit, along the line II-II.
  • a fuel delivery system shown in FIG. 1 has a fuel storage tank 10, from which a suction line 12 leads to the suction port 14 of a delivery unit 16.
  • the delivery unit 16 has a pressure port, not shown, via which the delivered fuel enters a pressure line 18, which leads to the internal combustion engine 20 of a motor vehicle.
  • the delivery unit 16 has an electric drive motor 22 which drives a delivery pump 24.
  • the feed pump 24 is designed as a so-called internal gear pump. It draws the fuel in from the storage tank 10 via the intake port 14 and presses it in the direction of the arrow 26 into a space 28 within the delivery unit 16, in which the electric drive motor 22 is accommodated.
  • a motor armature belonging to the electric motor 22 thus rotates in the fuel being pumped.
  • the conveyor unit 16 is a so-called
  • Inline unit with an attachment outside the fuel tank used.
  • this unit is also conceivable to use this unit as a so-called intank unit.
  • the delivery unit 18 is located within the storage tank 10, so that the suction line 12 can be omitted.
  • the feed pump 24 has a base plate 30 which, in the exemplary embodiment, also forms the end cover of a housing tube 32.
  • a second, so-called bearing cover 34 closes the other opening of the housing tube 32.
  • the housing parts 30, 32 and 34 enclose both the feed pump 24 and the electric motor 22.
  • the base plate 30 has a bearing pin 36 which is used to mount a pinion 38 belonging to the internal gear pump 24.
  • the toothing 40 of the toothed pinion 38 meshes with an internal toothing 42 of a toothed ring 44, the lateral surface 46 of which is guided in a bore 48 of a so-called annular intermediate or support plate 50.
  • On the end ring surface of the support ring 50 facing away from the base plate 30 lies one side of a cover plate 52, which in the exemplary embodiment simultaneously forms a bearing for an armature shaft 54 belonging to the electric motor 22.
  • the components 30, 50, 52 arranged fixed to the frame thus form, as it were, a pump housing or a chamber in which the conveying means 38, 44 moved by the drive motor 22 circulate.
  • the end of the armature shaft 54 facing the feed pump 24 passes through the cover plate 52 and engages with a driver 56 in the pinion 38 of the feed pump 24.
  • the pinion 38 of the internal gear pump 24 is driven so that it rotates on the journal 36. Via the toothing 40, the pinion 38 takes the toothed ring 44 with it, so that the internal gear pump 24 operates in a manner known per se. So that the undesirable noise formation of such pumps is at least greatly reduced, at least some of the parts 30, 50, 52, which form the multi-part pump housing 60, which is fixed in the housing 32, are made of a ceramic material. Depending on the application, the person skilled in the art will manufacture the base plate 30 and / or the cover plate 52 and / or the support plate 50 from the ceramic material. It is also conceivable to manufacture the support plate 50 in one piece with the base plate 30 or in one piece with the cover plate 52.
  • a partially stabilized zirconium dioxide is particularly suitable for producing the pump housing parts 30, 50, 52 mentioned.

Abstract

Il est proposé une unité (16) servant à l'alimentation en carburant à partir d'un réservoir (10) vers un moteur à combustion interne (20) de véhicule automobile. L'unité d'alimentation (16) comporte un moteur d'entraînement (22) électrique et une pompe d'alimentation (24) entraînée par ledit moteur. La pompe possède un corps (60) solidement fixé au carter de l'unité et formant une chambre. Dans ce corps de pompe tournent les organes mécaniques de la pompe mus par le moteur d'entraînement. On obtient une unité d'alimentation au fonctionnement particulièrement silencieux si au moins certaines pièces du corps de pompe, construit en plusieurs parties, sont fabriquées en matériau céramique.
