Definitions

  • the invention relates to a fuel delivery unit according to the preamble of patent claim 1.
  • a fuel delivery unit known from DE-OS 15 26 652 has an electric fuel pump which rests on the tank bottom via an elastic cushion and is suspended directly on the delivery pipe, this delivery pipe being of two parts and the two sections being connected to one another via a sleeve or sleeve .
  • This sleeve or sleeve can be, for example, a plastic tube or another elastic, flexible device. The pump is pressed against the tank bottom via the pipe section, the carrier pipe and the sleeve forming a kind of preload.
  • the pump is also suspended from the delivery pipe, but can move axially sufficiently and is supported either directly or via a separate support foot on the tank bottom with the aid of damping elements, which causes the pump to pulsate generated hydraulic oscillations and vibrations despite the damping elements through the direct connection of the pump to the feed pipe through this to the tank cap and thus the noise is not sufficiently prevented.
  • the object of the invention is to design a generic fuel delivery unit in such a way that the disadvantage shown no longer occurs.
  • the fuel delivery unit shown in Figure 1 consists of a fuel cap closure 1, to which a pressure line 2 and a return line 3 are fastened, the return line 3 having an upper part 4 and a lower part 6 loaded with a compression spring 5 supported on the fuel cap 1, which part is supported on the tank bottom 7, and an electric fuel feed pump 8, which is connected to the pressure line 2 and the lower part 6 of the return line 3 in an axially displaceable manner by means of an interconnected double telescopic guide 9. Furthermore, the fuel feed pump 8 is resiliently suspended in a bearing eye 10 of the lower part 6 and connected to the pressure line 2 via a damping element 11 designed as a bellows and has a filter element 12 at the lower end.
  • the oscillations and vibrations caused by the hydraulic pulsation are damped by means 13 in the bearing eye 10 and by the Pump 8 via the telescopic guide 9 with the pressure line 2 connecting, designed as bellows damping element 11, whereby the pressure line 2 is de-energized, so damped that noise transmission to the tank cap 1 and thus to the fuel tank is avoided.
  • a sealing ring 17 is advantageously arranged to seal the pressure line 2 in the region of the telescopic guide.
  • FIG. 2 shows, in addition to the axial fixation of the electric fuel delivery pump, spring elements 18 for radial fixation, the filter element 12 being designed as a damping element which rests on the tank bottom and has a greater spring stiffness than that between the electric fuel pump 8 and the telescopic part 9 attached bellows 11 has.
  • the filter element 12 is connected to the electric fuel pump via a further damping element 19.
