Definitions

  • the present invention relates to a cleaning fluid delivery device for a motor vehicle, including windshield washer fluid. It also relates to the use of the device for supplying liquid to at least one nozzle for a motor vehicle.
  • a washing liquid device heated or not, comprises
  • the invention aims to achieve these objectives.
  • the invention thus relates to a cleaning fluid delivery device for a motor vehicle.
  • the device according to the invention comprises a distribution element of
  • the cleaning liquid comprising at least one liquid inlet and at least two liquid outlets, a non-return valve adapted to prevent a fluid flow from each fluid outlet to each fluid inlet, the cleaning liquid conveying device further comprising heat-coupling means with the element liquid distribution.
  • the liquid distribution element may comprise at least one
  • the liquid distribution element may comprise for example two subassemblies each provided with a liquid inlet and two liquid outlets.
  • the heating means can be arranged between the two
  • the heating means may comprise at least one stone to
  • the invention also relates to the use of a device described
  • liquid distribution element comprising two subassemblies each provided with a liquid inlet connected to a non-return valve and two liquid outlets, for supplying liquid to a wiper system of a glazed surface comprising two brushes, each brush being equipped with a first nozzle to allow a liquid distribution of a first side of the brush during a rising phase of the sweep and a second nozzle to allow a liquid distribution on the other side of the broom during a downward phase of the sweeping, the liquid outlets of a sub-assembly of the liquid distribution element being intended to supply liquid first brush nozzles, the liquid outlets of the other subassembly being intended to supply liquid second brush nozzles.
  • FIG. 1 schematically illustrates a device for conveying cleaning liquid according to the invention
  • FIG. 1 is a general view of a liquid distribution element of the device.
  • Figures 3 and 4 are partial views of the liquid distribution element.
  • the automobile as shown in Figure 1, comprises a liquid distribution element 2.
  • the liquid distribution element 2 is connected upstream to a bidirectional pump 3, and is connected downstream to a passenger broom BP located on the passenger side, and to a conductor broom BC located on the driver's side.
  • the brushes BP and BC are each provided with a first nozzle for
  • the fluid distribution element 2 is placed before the connection with the pipes under the BP and BC arms.
  • the liquid distribution element 2 comprises two subassemblies 2A, 2B, between which is disposed a heating element 4.
  • the subassembly 2A comprises a liquid inlet fed with
  • a liquid outlet of the subassembly 2A is connected to the first nozzle of the brush BP, while the other liquid outlet of the subassembly 2A is connected to the first nozzle of the brush BC.
  • the subassembly 2B comprises an inlet of liquid supplied with liquid by the pump 3 and two liquid outlets.
  • a liquid outlet of the subassembly 2B is connected to the second nozzle of the brush BP, while the other liquid outlet of the subassembly 2B is connected to the second nozzle of the brush BC.
  • the pump 3 supplies liquid first sprinklers of the brushes BP and BC via the subassembly 2A.
  • the pump 3 supplies the second jets of the brushes BP and BC with liquid via the subassembly 2B.
  • the liquid distribution element 2 as shown in Figure 2, comprises the two subsets 2A and 2B. An opening is made between the two subassemblies to accommodate the known heating element 4.
  • the subset 2A comprises a part
  • the subassembly 2A also comprises a central zone 2A2 which is a zone for housing a check valve, as well as an upper zone 2A3 which is a separation zone of the two-part inlet channel, each leading to a fluid outlet.
  • Each fluid outlet may comprise a zone of rapid adaptation to a connector or a zone of direct connection to a pipe.
  • the non-return valve may be chosen from the known non-return valves, and in particular from the non-return valves with flap. guided, flying, double-leaf, ball or concentric discs.
  • the envelope of the lower zone 2A1 advantageously constitutes the cover of the non-return valve.
  • the heating element 4 it will advantageously be in thermal coupling with the zone 2A3 separating the input channel into two parts.
  • the subset 2B has the same structure as the subset 2A.
  • Each subassembly 2A, 2B may comprise at least two liquid outlets, the number of outlets being preferably equal to the number of brushes.
  • Each subassembly 2A, 2B can also have different shapes, for example T or V.
  • Figure 4 illustrates the intermediate zone between the subsets 2A and 2B in which is housed the heating element 4.
  • the heating element 4 is preferably a stone with a positive temperature coefficient. However, it would also be possible to use as a heating element a heating resistor, a resistive wire or any other heating element.
  • the heating temperature obtained by electrically feeding this type of thermistors is self-limited. More precisely, these thermistors rise in temperature until a substantially constant temperature value is obtained, corresponding to the so-called self-regulation temperature. It is therefore not necessary to provide a particular control device for the regulation of these elements.
