Definitions

  • Conveying device for conveying fuel from a fuel tank
  • the invention relates to a conveyor for conveying fuel from a fuel tank to a Brenn ⁇ engine of a motor vehicle with a Kraftstoffpum ⁇ pe, with a bottom valve having swirl pot and with a suction jet pump, wherein a suction port of the suction jet pump is connected to the fuel tank.
  • the suction jet pump is supplied with fuel as blowing agent via fuel returned by the internal combustion engine or via a branch of the supply line.
  • the suction jet pump is used to deliver fuel from the fuel tank ⁇ in the swirl pot.
  • the promotion of Saug ⁇ jet pump starts only when pump of the fuel ⁇ fuel can be pumped from the surge chamber.
  • a disadvantage of the known conveying device is that a first filling or refilling after a complete emptying of the fuel tank requires a large amount of fuel to be introduced into the fuel tank so that the swirl pot is also filled. Only then the fuel pump can draw fuel and the suction jet pump ⁇ operate. For a very large area of the bottom of the fuel tank, the initial charge requires several liters of fuel. In practice it has been shown that for the initial filling a level of 18 mm in the fuel tank is required so that the fuel pump ansau ⁇ gen can fuel.
  • the invention is based on the problem of the amount of force substance that is necessary during initial filling, reindeer of minimizing ⁇ .
  • the fuel pump is able to suck fuel directly from the fuel tank via the intake connection of the suction jet pump and the mixing tube after a first filling.
  • the suction pressure is sufficient with ein ⁇ switched fuel pump.
  • An operation of the suction jet pump is not required for this purpose.
  • Idle running of the baffle can be according to a ande ⁇ ren advantageous development of the invention is simple vermei ⁇ the is arranged when the bottom valve in the suction port of the ejector ⁇ pump and a negative pressure in the Ansaugan ⁇ circuit of the sucking jet pump in relation to the pressure at the bottom of the fuel tank in the Open position and at a pressure ⁇ balance in the closed position is movable.
  • the fuel pump can suck un ⁇ indirectly from the surge chamber fuel when in a connection of the mixing tube with the swirl pot an opening into the swirl pot overflow valve is arranged.
  • connection of the surge pot to the suction port of the fuel pump is opened in accordance with another advantageous development of the invention even at low levels in the surge pot when the float of the spill valve is located near the bottom of the baffle. This ensures that can be sucked fuel pump with an empty fuel tank near ⁇ to all of the fuel from the surge chamber of the force.
  • the filling of the surge pot is reliably ensured if the relief valve is designed as a pressure relief valve, which at a relative to the pressure in the bottom region of Swirl pot high pressure in the mixing tube opens. As a result, excess fuel conveyed by the suction jet pump flows via the overflow valve into the surge pot.
  • a mixing chamber is arranged when the mixing chamber has a nozzle of the suction jet pump and a connection for the mixing ⁇ pipe of the suction jet pump and when the bottom valve opens into the mixing chamber.
  • the overflow valve could for example also be arranged on the mixing chamber.
  • An intake of fuel from the surge pot by the suction jet pump can be according to another advantageous embodiment of the invention ein ⁇ fold prevent when the overflow valve is arranged on the mixing tube.
  • the bottom valve and / or the overflow valve capable, according to another advantageous development of the invention there are advantages to control when the Bo ⁇ denventil and / or the spill valve abde an opening / ⁇ ADORABLE having plate-shaped member having.
  • a further advantage of this design is that the bottom valve or the overflow valve thereby require a particularly small installation space.
  • the leadership of the plate-shaped member of the bottom valve and / or the spill valve according to another advantageous embodiment of the invention requires a particularly ge wrestle structural complexity when the plate-shaped member is connected to a guide shaft.
  • the Filterele ⁇ ment also allows an exclusive flow of power ⁇ material and prevents in case of leakage of the overflow valve or in an empty swirl pot penetration of air into the mixing tube.
  • the suction jet pump is arranged next to the fuel pump.
  • FIG. 1 shows schematically a sectional view through a
  • FIG. 2 greatly enlarges a partial region of the delivery device from FIG. 1.
  • FIG. 1 shows a fuel tank 1 in a sectional view with a swirl pot 2 arranged therein.
  • a fuel pump 3 is arranged in the swirl pot 2, which fuel is supplied via a feed line 4 to an internal combustion engine. 5 engine of a motor vehicle promotes.
  • a suction jet pump 6 is arranged, which is supplied via a connected to the flow line 4 branch 7 with fuel as a propellant.
  • the eductor 6 comprises a Mün into a mixing chamber 8 ⁇ Dende nozzle 9, and is greatly enlarged in Figure 2 Darge ⁇ represents.
  • the mixing chamber 8 has a connector 10 for a mixing tube 11 and a bottom valve 12.
  • the mixing tube 11 leads to the position shown in Figure 1 fuel pump 3.
  • the bottom valve 12 has a valve body 14, which closes or releases an opening 15 in the bottom of the swirl pot 2. So that the opening 15 in the bottom of the baffle 2 forms a check suction port 16 of the ejector pump 6.
  • the mixing tube 11 has an overflow valve 17 which includes a valve ⁇ body 18 a leading to the surge chamber 2 opening 19 ver ⁇ or releases ,
  • the valve body 18 of the overflow valve 17 is connected to a float 20.
  • the bottom valve 12 and the overflow valve 17 are each covered by a feinma ⁇ cal filter element 21, 22.
  • valve bodies 14, 18 of the spill valve 17 and the bottom valve 12 each have ⁇ wells a plate-shaped member 23, 24 and connected to the plate-shaped member 23, 24 guide shaft 25, 26 is guided by the movement of the plate-shaped member 23, 24 ,
  • the overflow valve 17 is also moved by the float 20 at a corresponding level in the swirl pot 2 in the open position.
  • the suction jet pump 6 sucks fuel through the bottom valve 12 and promotes this in the mixing tube 11 to the fuel pump 3.
  • the fuel pump 3 with empty baffle 2 and a very small amount of fuel in the fuel tank ⁇ 1 draw fuel. If more fuel is delivered from the ejector pump 6 as a fuel pump 3 reaches excess fuel consumed by the over ⁇ strömventil 17 in the surge chamber 2.
  • the over ⁇ strömventil 17 in the surge chamber 2 At sufficiently filled j ⁇ tem surge chamber 2 also moves the float 20, the Koch ⁇ strömventil 17 in the open position.
  • the fine-meshed filter elements 21, 22 are coated with Teflon, for example, and are exclusively permeable to fuel and prevent the passage of air.

Abstract

L'invention concerne un dispositif de transport destiné au transport de carburant à partir d'un réservoir de carburant (1). Une tubulure d'admission (13) d'une pompe à carburant (3) est reliée à un tuyau mélangeur (11) d'une pompe à jet aspirant (6). La pompe à jet aspirant (6) aspire du carburant du réservoir de carburant (1) par une soupape de fond (12). Le tuyau mélangeur (11) a une soupape de trop-plein (17) qui commande une liaison avec le réservoir interne (2). La pompe à carburant (3) peut ainsi aspirer du carburant du réservoir de carburant (1) lorsque le réservoir interne (2) est vide.
