Definitions

  • the present invention relates to the field of systems for drawing fuel from a motor vehicle tank.
  • systems for drawing fuel from a motor vehicle tank comprise an electric pump which sucks fuel in from the tank or from a supply situated within the tank.
  • the object of such a supply is to limit the amount of fuel movement in the vicinity of the suction inlet of the pump, as can result from acceleration, deceleration, or centrifugal force whenever the vehicle is not following a rectilinear path.
  • known fuel-drawing systems generally include a coarse filter or strainer placed at the inlet of the pump, and a fine filter for guaranteeing the quality of the fuel that is forwarded to the engine.
  • the fine filter is sometimes the subject of significant clogging if it is placed upstream from the pump, particularly when the electric pump is associated with a supply which is itself fed by a jet pump, for example, receiving an inlet flow coming directly or indirectly from the outlet of the electric pump.
  • Turbine or centrifugal pumps are machines in which the rotation of a wheel or a rotor generates pressure and speed conditions that determine how a liquid flows in a circuit, with the magnitude of the flow being the result of equilibrium between the useful energy delivered by the pump per unit mass and the resistive energy per unit mass of the circuit.
  • turbine or centrifugal pumps generally possess a degassing orifice.
  • the presence of such a degassing orifice on the pump housing leads to contamination not only of the inside volume of the pump, but also of at least a portion of the volume of the fine filter housing connected thereto.
  • An object of the present invention is to improve known fuel-drawing systems in order to eliminate the above-specified drawbacks that are inherent to the prior art.
  • this object is achieved by a device for drawing-off fuel from a motor vehicle tank, the device comprising a drawing-off pump and a fine filter placed upstream from the pump, wherein the drawing-off pump is a brush-less pump.
  • the drawing-off pump is a pilot operated pump.
  • the drawing-off pump is pilot operated in such a manner that the flow of fuel passing through the pump is close to the minimum flow required for proper operation of the device.
  • FIG. 1 is a diagrammatic vertical section view through a drawing-off device constituting a first embodiment of the present invention
  • FIG. 2 is a similar vertical section view of a device constituting a second embodiment of the present invention.
  • FIG. 3 is a similar vertical section view of a third embodiment of the present invention, shown on non-coplanar planes referenced 3 - 3 in FIG. 4;
  • FIG. 4 is a horizontal cross-section view through the FIG. 3 device
  • FIG. 5 is a diagrammatic longitudinal axial section view through a conventional jet pump of the prior art
  • FIG. 6 is a diagrammatic longitudinal axial section view of a jet pump in accordance with the present invention.
  • FIG. 7 is a diagrammatic longitudinal axial section view of a jet pump constituting a preferred variant of the present invention.
  • the device of the present invention comprises an electric drawing-off pump 100 and a fine filter 210 placed upstream from the pump, i.e. at the inlet thereof.
  • the drawing-off pump 100 is a brush-less electric pump.
  • a pump is well known to the person skilled in the art. Essentially, it comprises a stator with coils and a rotor with a magnet.
  • a brush-less pump 100 makes it possible to limit the risk of allowing foreign bodies to enter into the fuel or the injectors, and in particular shavings of metal or of plastics material that might be torn off during displacement of the brushes on an associated collector, in a conventional pump with brushes.
  • the drawing-off pump 100 is preferably a pilot operated pump.
  • the drawing-off pump 100 is pilot operated in such a manner that the flow of fuel passing through it, and consequently also passing through the fine filter 210 placed upstream therefrom, is substantially equal to the flow required for proper operation as a function of the instantaneous consumption of the engine.
  • the drawing-off pump 100 sucks from a supply fed by a jet pump that receives an inlet flow coming directly or indirectly from the outlet of the drawing-off pump
  • the drawing-off pump is pilot operated so as to deliver a flow that varies in such a manner that the flow passing through it and through the fine filter is substantially equal to the sum of the instantaneous consumption of the engine plus the auxiliary flow required for enabling the jet pump to operate.
  • instantaneous consumption of the engine is used herein to mean the actual instantaneous consumption of the engine, plus, where appropriate, any additional flow Qr that needs to be sent towards the engine in order to ensure that its injectors operate properly, but that is not actually consumed in practice, being returned to the drawing-off point (see FIG. 1)).
  • the drawing-off pump 100 takes fuel directly from the tank
  • the drawing-off pump is pilot operated so as to deliver a flow that varies in such a manner that the flow which passes through the pump and through the fine filter is substantially equal to the instantaneous consumption of the engine.
  • instantaneous consumption of the engine is used to mean the effective instantaneous consumption of the engine plus, where appropriate, any additional flow Qr that is sent to the engine in order to ensure that its injectors operate properly, but that is not consumed in practice, being returned to the drawing-off point (see FIG. 1)).
  • the present invention serves to limit the flow rate through the fine filter 210 , and therefore serves to limit the head losses through the filter 210 , the pressure at the inlet to the fine filter, the inlet pressure to the pump 100 , and also clogging of the fine filter 210 .
  • the drawing-off pump 100 can be pilot operated in various different ways.
  • the drawing-off pump 100 can be pilot operated by a pressure or flow rate sensor placed at the outlet from the pump.
  • a pressure or flow rate sensor placed at the outlet from the pump.
  • such a technique for regulating a pump is known to the person skilled in the art. It is therefore not described in detail below. It is merely recalled at this point that such regulation generally requires the pump to deliver some minimum flow rate on a continuous basis in order to ensure that it operates properly.
  • the drawing-off pump 100 can be pilot operated by a reference coming from an engine control module, which reference is representative of the instantaneous consumption required by the engine. Under such circumstances, the pump 100 can be pilot operated from the control signal on the basis of curves of the pressure/flow rate or electrical current/speed kind.

  • the radially inner cylindrical wall 204 which defines the outlet chamber 250 and which is interrupted beyond the partition 207 is extended by a horizontal wall 209 parallel to the abovementioned partition 207 .
  • the two partitions 207 , 209 thus define a cylindrical chamber 205 which communicates with the outlet chamber 250 of the filter housing.
  • the inlet 110 of the pump opens out into said chamber 205 .
  • the partition 209 surrounds the inlet 110 of the filter in leaktight manner.
