Definitions

  • the invention relates to a fuel pump for delivering fuel into a fuel tank of a motor vehicle, having a driven impeller rotating in a housing, with rings of guide blades defining blade chambers arranged on both end faces of the impeller, opposing blade chambers being connected to one another, with partially annular ducts, which are arranged in the area of the guide blades in an inlet-side housing part and in an outlet-side housing part and which together with the blade chambers form a delivery chamber for delivering a liquid from an inlet duct to an outlet duct, one of the partially annular ducts being connected to the inlet duct and the other, the opposing partially annular duct, being connected to the outlet duct.
  • Such fuel pumps are known as peripheral or side-channel pumps and are often used in the fuel tanks of present-day motor vehicles.
  • the partially annular ducts extend over an angular range of approximately 300 to 330°.
  • a disadvantage of the known fuel pumps is that vortices occur in the area of the blade chambers as the delivered liquid flows over. These vortices lead to a low efficiency of the fuel pump and lead, particularly when delivering hot fuel, to gassing of the fuel. The gassing leads to a further reduction in the efficiency of the fuel pump.
  • the object of the invention is to design a fuel pump of the type described in the introductory part so that it has a maximum possible efficiency.
  • this object is achieved in that the partially annular duct in the inlet-side housing part continuously narrows away from the inlet duct and/or the partially annular duct in the outlet-side housing part continuously widens toward the outlet duct, and that the continuous narrowing or widening extends over at least 80% of the length of the corresponding partially annular duct.
  • This design allows the liquid being delivered to be continuously transferred from the partially annular duct in the inlet-side housing part to the partially annular duct in the outlet-side housing part. This also makes it possible to generate a uniform rise in pressure increasing toward the outlet duct in the two partially annular housing parts. This means that there is a uniform flow through the opposing blade chambers as they move from the inlet duct to the outlet duct. This serves to prevent the rate of flow as the liquid flows over from one blade chamber into the opposing blade chambers increasing the closer these blade chambers get to the outlet duct, as is the case in the known fuel pump.
  • the fuel pump according to the invention therefore has an especially high efficiency.
  • the narrowing or widening of the partially annular ducts is particularly easy to configure if at least one of the partially annular ducts is of wedge-shaped design in a section along the delivery chamber.
  • the delivery chamber has substantially the same cross-section at any point, the cross-section of the partially annular duct in the inlet-side housing part being larger in proximity to the inlet duct than the cross-section of the partially annular duct in the outlet-side housing part.
  • FIG. 1 shows a fuel delivery unit for a motor vehicle having a fuel pump according to the invention
  • FIG. 2 shows a tangential, sectional representation through the fuel pump in the area of a delivery chamber.
  • FIG. 1 shows a fuel delivery unit intended to be arranged in a fuel tank of a motor vehicle and having a housing 1 and a fuel pump 3 in the form of a side-channel pump driven by an electric motor 2 .
  • the fuel pump 3 has an impeller 6 arranged between an inlet-side housing part 4 and an outlet-side housing part 5 .
  • An inlet duct 7 is arranged in the inlet-side housing part 4 and an outlet duct 8 in the outlet-side housing part 5 .
  • the impeller 6 is fixed on a shaft 9 of the electric motor 2 .
  • the fuel pump 3 has opposing rings of guide blades 11 defining blade chambers 10 on both end faces of the impeller 6 .
  • the housing parts 4 , 5 each have a partially annular duct 12 , 13 in the area of the blade chambers 10 .
  • the partially annular ducts 12 , 13 together with the blade chambers 10 form a delivery chamber 14 leading from the inlet duct 7 through the impeller 6 to the outlet duct 8 .
  • the inlet duct 7 and the outlet duct 8 are shown turned into the plane of projection.
  • the delivery chamber 14 extends over an angular range of approximately 300 to 330°.
  • the impeller 6 rotates the guide blades 11 produce a circulatory flow, running transversely to the direction of movement of the guide blades 11 , in the delivery chamber 14 . In so doing the delivered fuel flows over from the inlet-side housing part 4 to the outlet-side housing part 5 through the interconnected blade chambers 10 .
  • FIG. 2 in a tangential section through the fuel pump in FIG. 1 in the area of the delivery chamber 14 , shows that the partially annular duct 12 arranged in the inlet-side housing part 4 narrows away from the inlet duct 7 , viewed in the direction of flow.
  • the partially annular duct 13 arranged in the outlet-side housing part 5 furthermore widens toward the outlet duct 8 viewed in the direction of flow.
  • the widening and narrowing extend virtually over the entire length of the partially annular ducts 12 , 13 and each virtually have a wedge shape.
  • the partially annular ducts 12 , 13 widen and narrow to the same degree, so that over the whole area of the partially annular ducts 12 , 13 the delivery chamber 14 has substantially the same cross-section.
