Definitions

  • the invention relates to a fuel pump for conveying fuel into a fuel tank of a motor vehicle with a driven, rotating in a housing impeller, arranged at both ends of the impeller wreaths blade chambers bounding vanes, wherein opposing vane chambers are interconnected, with in the region of the vanes arranged in an inlet-side housing part and an outlet-side housing part, part-annular channels which form a conveying chamber with the blade chambers for conveying a liquid from an inlet channel to an outlet channel, wherein one of the partially annular channels with the inlet channel and the other, the opposite partial annular channel with the outlet channel connected is.
  • a fuel pump according to the preamble of claim 1 is known from DE-A-4427874 ,
  • Such fuel pumps are known as peripheral or side channel pumps and are commonly used in fuel tanks of today's motor vehicles.
  • the part-annular channels extend over an angular range of about 300 to 330 °.
  • the invention is based on the problem to design a fuel pump of the type mentioned so that it has the highest possible efficiency.
  • the liquid to be conveyed can be continuously transferred from the partially annular channel in the inlet side housing part to the partially annular channel in the outlet side housing part.
  • This also makes it possible to produce a uniform increase in pressure to the outlet channel in the two part-annular housing parts.
  • the opposing blade chambers are therefore flowed through evenly during their movement from the inlet channel to the outlet channel. Therefore, it is avoided that the flow velocity, as in the known fuel pump, the greater the overflow from the one vane chamber into the opposing vane chambers, the more these vane chambers approach the exhaust duct.
  • the fuel pump according to the invention therefore has a particularly high efficiency.
  • the cross-section of the partially annular channel in the inlet-side housing part is greater than the cross-section of the partially annular Channel in the outlet-side housing part.
  • FIG. 1 shows a provided for arrangement in a fuel tank of a motor vehicle fuel delivery unit with a housing 1 and a driven by an electric motor 2, designed as a side channel pump fuel pump 3.
  • the fuel pump 3 has an arranged between an inlet-side housing part 4 and an outlet-side housing part 5 impeller on.
  • an inlet channel 7 and in the outlet-side housing part 5, an outlet channel 8 is arranged.
  • the impeller 6 is mounted on a shaft 9 of the electric motor 2.
  • the housing parts 4, 5 each have a partially annular channel 12, 13.
  • the partially annular channels 12, 31 form with the Bucket chambers 10 a guided from the inlet channel 7 through the impeller 6 to the outlet channel 8 delivery chamber 14.
  • the inlet channel 7 and the outlet channel 8 are shown rotated in the plane of drawing for simplicity.
  • the delivery chamber 14 extends over an angular range of about 300 to 330 °.
  • the guide vanes 11 in the delivery chamber 14 generate a circulation flow running transversely to the direction of movement of the guide vanes 11.
  • the delivered fuel flows from the inlet-side housing part 4 to the outlet-side housing part 5 through the interconnected blade chambers 10.
  • FIG. 2 shows in a tangential section through the fuel pump FIG. 1 in the region of the delivery chamber 14, that the partially annular channel 12 arranged in the inlet-side housing part 4 decreases, starting from the inlet channel 7, as seen in the direction of flow. Furthermore, the partially annular channel 13 arranged in the outlet-side housing part 5 increases in the direction of flow toward the outlet channel 8.
  • the flows of the fuel and the direction of movement of the rotor 6 are indicated by arrows in the drawing.
  • the enlargement and reduction extend almost over the entire length of the part-annular channels 12, 13 and each have almost a wedge shape.
  • the enlargement and reduction of the part-annular channels 12, 13 takes place by the same amount, so that the delivery chamber 14 over the entire region of the part-annular channels 12, 13 has substantially the same cross-section.
