Definitions

  • the invention relates to a suction jet pump with improved suction.
  • Suction jet pumps are used for example in fuel tanks of Motor vehicles used to fuel from an area of the fuel tank to promote another area.
  • Suction jet pumps are nowadays in fuel tanks of motor vehicles used and are known. You have the job of fuel off distant and deeper areas of the fuel tank to the conveyor unit or to promote it in a swirl pot.
  • the suction jet pump consists essentially from a motive jet pipe, a suction opening and a Mixing tube.
  • the quantity supplied via the motive jet tube of the ejector pump on liquid occurs under pressure from the fürstrahlrohr limiting Drive jet nozzle off and then into the mixing tube.
  • the intake opening for the liquid to be conveyed is between the propulsion jet and the Mixing tube arranged.
  • the entering into the mixing tube maschinehl generated before the mixing tube a negative pressure, so that the liquid to be conveyed on the Suction opening is sucked into the mixing tube.
  • the efficiency of a Suction jet pump depends on many factors. For example, influence the length of the mixing tube and other geometric factors Efficiency.
  • the general disadvantage of suction jet pumps consists in its relatively low efficiency of about 20 up to 30%.
  • the invention is therefore based on the object, a suction jet pump to create with improved suction, the is simple and does not take up much space.
  • the problem is solved with the features of claim 1.
  • Advantageous embodiments are in the claims 2 to 8 described.
  • suction jet pump according to the invention consists in their known suction jet pumps improved suction, the on the fast liquid closure in the diffuser is returned.
  • suction jet pump owns a very simple structure and requires little Space.
  • the diffuser in this case an elliptical adapted to the flat jet Intake cone.
  • a nozzle opening which is a transversely has extending notch.
  • the propulsion jet is fan-shaped widened.
  • the Nozzle opening arranged a web that divides the propulsion jet and thus generates the flat jet.
  • FIG. 1 a section through an inventive suction jet pump
  • Figure 2 shows the top view on the mixing tube with elliptical diffuser.
  • the suction jet pump shown in Figure 1 consists of a Upper part 1 and a lower part 2.
  • the upper part 1 has a Connecting piece 3 for a jet jet line, not shown, through which the propellant of the suction jet pump is supplied.
  • At the connection piece 3 closes the Examstrahldüse 5 with its nozzle opening 6 at.
  • a cross extending notch 7 causes the fan-shaped expansion of the Driving jet.
  • the lower part 2 of the suction jet pump is from Mixing tube 8 and the diffuser 9 is formed, wherein the diffuser. 9 in an inner housing part 10 passes.
  • This inner housing part 10 is inserted into the outer housing part 4 latching and by means of a sealing ring 11 with the upper part of the first tightly connected.
  • a suction port forming nozzle 12 At the periphery of the inner housing part 10 is arranged a suction port forming nozzle 12, via the liquid sucked into the suction jet pump and the mixing tube in a likewise not shown line is promoted.
  • a suction port forming nozzle 12 For easy installation of the suction jet pump are on the upper part 1 two resilient locking hooks 13 formed the can be deflected by pressing the spring arms 14.
  • FIG. 2 shows the lower part 2 with the inner housing part 10 and the elliptical formed diffuser 9, which merges into the cylindrical mixing tube 8.
  • the nozzle 12 is arranged at an angle of 90 ° to the inner housing part 10.
