Definitions

  • the invention relates to a fuel supply device according to the preamble of claim 1.
  • a fuel supply device in which an electronically controlled fuel pump promotes fuel from a fuel reservoir to an internal combustion engine.
  • a pressure limiting device is connected downstream of a pressure sensor and controlled such that the fuel pressure is approximately equal to a desired pressure.
  • the pressure limiting device opens and delivers fuel into a return line.
  • a suction jet pump is connected in the return line.
  • the invention has for its object to provide a fuel supply device with which any Abstelltik can be realized.
  • the object is achieved by the features of claim 1.
  • a second pressure limiting device for supplying fuel to an internal combustion engine, in addition to an at least first pressure limiting device, a second pressure limiting device is provided, whose reference port influencing its opening pressure is acted upon by pressure of a supply line, which is arranged upstream of a check valve.
  • This has the advantage that the opening pressure of the second pressure limiting device and thus also the shutdown pressure of the fuel supply device can be chosen arbitrarily.
  • the second pressure limiting unit is deactivated while the fuel pump is running.
  • the second pressure-limiting unit can open at significantly lower pressures than the first pressure-limiting unit.
  • the check valve in the supply line is expediently arranged upstream of the fuel filter.
  • the second pressure limiting device is arranged with its reference port upstream of the arranged in the flow line check valve and the fuel filter. It is equally expedient to arrange the second pressure limiting device downstream of the fuel filter.
  • the flow line is drivingly connected to a first suction jet pump.
  • the first pressure limiting device downstream in a branch line of a high pressure line of the fuel filter is arranged.
  • the first pressure limiting device opens at a pressure which corresponds at least to the maximum system pressure.
  • the single figure shows schematically a preferred KraftStoffVersorgungs thanks according to the invention.
  • a pump control unit 19 is connected to the fuel pump 15 via electrical lines 18 for electronic control.
  • the fuel reservoir 11 has a first chamber 12 and a second chamber 13 and is configured overall as a saddle tank.
  • a swirl pot 14 is provided, in which the fuel pump 15 is arranged.
  • Fuel from the first chamber 12 is directed via a first suction jet pump 16 into the surge pot 14, which is driven by a Kraftstoffström from a flow line 26.
  • a check valve 20 protects the upstream components of the fuel supply 10 from fuel flowing back out of the fuel filter 21.
  • a branch line 28 leads from the feed line 26 to a second suction jet pump 17, which sits in the second chamber 13 of the fuel tank 11 and conveys the fuel via a connecting line 29 from the second chamber 13 into the first chamber 12.
  • the second suction jet pump 17 is thus as well as the first suction jet pump 16 driven by fuel from the flow line 26.
  • a first pressure-limiting device 22 is arranged in a branch line 31 branching off from a high-pressure line 30.
  • the high pressure line 30 leads downstream of the fuel filter 21 to the storage space 23.
  • This pressure limiting device 22 opens only at a high pressure which corresponds at least to the maximum system pressure, or preferably greater than the maximum system pressure.
  • a second pressure-limiting device 24 is provided in a branch line 32 branching off from the high-pressure line 30, whose reference port 25 is acted upon by pressure of the branch line 28, which is arranged upstream of the check valve 20 and from which the feed line 26 branches off.

Abstract

L'invention concerne un dispositif d'alimentation en carburant servant à alimenter un moteur à combustion interne en carburant. Ce dispositif d'alimentation en carburant comprend : au moins une pompe à carburant à entraînement électrique (15) qui transporte du carburant, d'un réservoir de carburant (11) vers le moteur à combustion interne, par l'intermédiaire d'un filtre à carburant (21), et ; au moins un dispositif de limitation de pression (22). La pression d'arrêt du dispositif d'alimentation en carburant peut être régulée librement lorsqu'un deuxième dispositif de limitation de pression (24) est prévu. Le raccord de référence (25) de ce deuxième dispositif de limitation de pression, qui influe sur la pression d'ouverture, est soumis à la pression d'une conduite montante (26) qui est montée en amont d'une soupape de non-retour (20).
