Definitions

  • the present invention relates to the field of sets of drawing fuel from a motor vehicle tank.
  • Most known devices include a pump electric associated with a pressure regulator.
  • the jet pump is generally supplied by an output stage of the main pump or through the outlet of the pressure regulator. She sucks fuel in the tank and its outlet opens into the reserve bowl.
  • Document EP-A-0798 458 describes a pumping device intended to be immersed in a tank for motor vehicles comprising a main body in which two contiguous cavities are arranged, the first has its main opening up and contains a subset pumping and the second of which has its main opening on the side and contains a filter cartridge, said cavity being connected to a fixing plate by a conduit to that of the plate for supplying vehicle fuel, while a pressure regulator is disposed of side of the main opening of the cavity and is associated with a typical system jet pump which opens into the first cavity.
  • the present invention now aims to provide new means of drawing fuel with performance improved compared to known devices.
  • the present invention makes it possible to facilitate adjustment of the jet pump / regulator sub-assembly, in relation to to known prior arrangements.
  • the invention also relates to fuel tanks for motor vehicle equipped with such a drawing assembly.
  • a drawing module 100 is placed in the tank 10.
  • this drawing module 100 comprises a pump electric 110, primary filter 120, secondary filter 130, regulator pressure 170 and a jet pump 160.
  • the electric pump 110 has its vertical axis. Its input is connected primary filter 120 located near the bottom of tank 10, plus precisely inside the reserve bowl 150 as will be specified by the after.
  • the output of the electric pump 110 flows into the secondary filter 130 which constitutes a finer filter than the primary filter 120.
  • the secondary filter 130 is an annular filter disposed around the pump 110.
  • the fuel coming from the main pump 110 passes through radially the filter 130, from the outside towards the inside of it (however the reverse arrangement is possible, i.e. the pump outlet 110 can flow on the inside of the filter 130 in which case the fuel passes through radially outwards the latter).
  • the filtered fuel is directed by through a conduit 132 to a pipe 140 carried by a base 142 intended to be fixed on the upper wall 14 of the tank. From there, the fuel is directed through a conduit 144 to the injector rail 20.
  • the primary filter 120 in which sucks the inlet of the pump 110 is arranged in the reserve bowl 150.
  • the latter rests on the tank bottom wall 12 by via feet 152 of low height.
  • the reserve bowl 150 is designed to be filled by the jet pump 160 associated with the pressure regulator 170.
  • this pressure regulator 170 has a housing 171 which houses a membrane 172. According to the particular embodiment illustrated in Figure 1, the input of the regulator housing 170 is connected to the output of the secondary filter 130.
  • the membrane 172 is subjected to the opposing forces of a spring tared 173 and the fuel pressure applied via the input of regulator 170.
  • the membrane 172 carries a shutter 174 associated with a fixed seat 175.
  • the shutter 174 rests on the seat 175 and the regulator 170 is closed. The jet pump 160 is then not supplied.
  • the output of the regulator 170 communicates with the entrance of a sprinkler 162.
  • the jet pump 160 further comprises a suction duct 164 which communicates with the bottom of the tank 10 and whose outlet opens in the body of the jet pump 160 downstream of the nozzle 162.
  • the outlet of the jet pump 160 itself opens out inside the bowl 150.
  • the outlet of the jet pump 160 is associated with means for degassing the fuel before it reaches the fuel bowl reserve 150.
  • a wall can be provided 154 opposite the outlet of the jet pump 160.
  • This wall 154 is connected by sealing laterally and at its base to the walls forming the bowl of reserve 150.
  • the fuel coming from the jet pump 160 thus strikes the low wall 154.
  • any air bubbles conveyed with the fuel in the jet pump 160 are broken.
  • the wall 154 thus defines the maximum level inside the reserve bowl 150 in the non-powered state of the jet pump 160.
  • such a low wall 154 can be replaced by a spiral staircase with rising bottom, the inlet of which is placed opposite the outlet of the jet 160 and the outlet of which opens into the reserve bowl 150.
  • the fuel is degassed gradually as it flows over it spiral.
  • the input of the regulator 170 connected at the output of the secondary fine filter 130 according to FIG. 1 could be connected by upstream of the fine filter 130.
  • This wall 2 shows the wall of the reserve bowl 150, the filter secondary end 130 disposed in a housing 131, the regulator 170 comprising a housing 171, a membrane 172 associated with a spring 173 and which carries a shutter 174 cooperating with a seat 175, as well as the jet pump 160 comprising a nozzle 162 and a suction duct 164.
  • the shutter 174 carried by the membrane 172 is formed by a spherical ball.
  • the seat 175 and the nozzle 162 are formed at the ends of a single piece made of preferably by filming.
  • the geometry of the body of the jet pump 160 can be the subject of many variations depending on the pump characteristics sought.
  • the jet pump 160 has its horizontal axis.
  • the jet pump 160 (as well as the regulator 170) has its axis inclined on the horizontal in approximation of the bottom 12 of the tank towards the outlet of the nozzle 162.
  • This arrangement makes it possible to reduce the suction height and priming the jet pump 160.
  • the axis of the jet pump 160 can thus be inclined typically around 18 ° on the horizontal.
  • This arrangement typically reduces the height for priming the jet pump 160 at a height A of the order of 6.4 mm for the variant embodiment illustrated in FIG. 3 with respect to a priming height A of the order of 15.7 mm for the embodiment illustrated in figure 2.
  • the jet pump 160 may include a section nozzle variable.
  • It may for example be a jet pump in which the nozzle which receives the injected flow is formed by a nozzle composed of several lips of elastic material adapted so that the nozzle has a variable section depending on the pressure and flow injected, as proposed by the Applicant in its patent application filed in France on 26 September 1996 under n ° 96 11739.
  • a jet pump 160 comprising a nozzle 162 and a core 165 mounted in displacement opposite the nozzle outlet nozzle 162, and in downstream of it.
  • the core 165 can be provided with a longitudinal through channel 166 forming a auxiliary nozzle.
  • the core 165 can be guided in translation along the axis of the pump jet 160 by any suitable known means. Of course, these means of guidance must not disturb the flow of fuel from the nozzle 162 and sucked in through suction pipe 164.
  • the core 165 is biased towards the outlet of the nozzle 162 by a calibrated spring 167.
  • the core 165 rests on the free end of the nozzle 162 in the form of an area limited substantially to a circular edge or on a contact generator defined on the nozzle 162.
  • the ejection section i.e. the free section of the nozzle 162 is reduced and makes it possible to increase the power transmitted to the jet pump by a high injection pressure.
  • the core 165 backs up by compression of the spring 167, with respect to the nozzle 162 which allows increase the passage section at the outlet of the nozzle 162 and limit the against pressure upstream of the nozzle 162 at an acceptable level.
  • the fuel drawing assembly according to the present invention is further equipped with means for fuel level gauging in the conventional tank 10 per se.
