Definitions

  • the invention relates to a peripheral pump according to the preamble of the main claim.
  • a peripheral pump is already known (US-A-3 315 607), in which the common center of the two circular sections lies on the axial gap between the impeller and the chamber wall.
  • US-A-3 315 607 the common center of the two circular sections lies on the axial gap between the impeller and the chamber wall.
  • the efficiency of such peripheral pumps cannot be satisfactory.
  • peripheral pump according to the invention with the characterizing features of the main claim has the advantage that the pump output is increased to a satisfactory level because the circulation flow Qc can be increased by approximately 20% under otherwise identical conditions. This means that the maximum delivery pressure can be increased accordingly with the same external dimensions and operating conditions.
  • FIG. 1 shows a fuel delivery unit with a peripheral pump shown in longitudinal section
  • FIG. 2 shows a detail of the peripheral pump denoted by II in FIG. 1, on an enlarged scale
  • FIG. 3 shows a cross section through the peripheral pump according to FIG. 1, along the line III-III and
  • FIG. 4 a graph showing the increase factor for the circulation flow as a function of ⁇ .
  • FIG. 1 An assembly 10 shown in FIG. 1 is used to deliver fuel from a storage tank (not shown) to the internal combustion engine (also not shown) of a motor vehicle.
  • the fuel delivery unit 10 has a flow pump 12, the impeller 14 of which is rotatably connected by a shaft 16 driven by an electric drive motor (not shown).
  • the impeller 14 is seated on a bearing journal 18 and is arranged in a so-called pump chamber 19 which - seen in the axial direction of the impeller 14 - is delimited on both sides by walls 20 and 22.
  • the bearing pin 18 is arranged on the wall 20.
  • the wall 22 has a bearing point 24 for the drive shaft 16.
  • the flow pump 12 draws fuel through a suction port 26 and presses this medium via a pump outlet 28 in the wall 22 into a space 30 in which the electric motor (not shown) is accommodated. From there the fuel is supplied to the internal combustion engine via an outlet or pressure port 32. Since both the flow pump 12 and the electric motor, not shown, are accommodated in a common housing 33, which is provided with a suction port 26 and a pressure port 32 and the fuel thus flows through the fuel delivery unit 10, the fuel delivery unit forms part of the delivery line of the vehicle Storage tank for the internal combustion engine.
  • curve 75 was assumed for R 17.5 mm and for A 4.52 mm2.
  • curve 80 the value 17.5 mm was retained for R and A was increased to 5.31 mm2.
