Abstract

The invention relates to a component (10) for a system (9) for supplying and/or distributing a liquid for a wiping apparatus for a motor vehicle, including a space, defined by a wall, in which the liquid can be accommodated, characterized in that the wall is made of a plastic heat-conducting material. The invention can be used for motor vehicles.

First claim

The invention claimed is:

1. A component of a liquid supply and/or distribution system of a wiping installation for a motor vehicle, comprising:
a space delimited by a wall in which the liquid spreads, wherein the wall is made of a heat-conducting plastic material; and
a dedicated heat source in physical contact with the wall, wherein the dedicated heat source is a resistive and heating track that extends along an outer face of the wall,
wherein the plastic material is a polyethylene charged with nanofibers and exhibits a thermal diffusivity greater than or equal to 0.00019 m 2 /s.

2. The component as claimed in claim 1 , the component forming a liquid retention tank, said wall comprising at least one orifice for filling said space with liquid and at least one hole suitable for receiving a pump for circulating the liquid in the supply and/or distribution system.

3. The component as claimed in claim 1 , the component forming a pump for circulating the liquid in the supply and/or distribution system.

4. The component as claimed in claim 1 , the component forming a hydraulic coupling between a pump for circulating the liquid and at least one constituent liquid transport and heating tube of the liquid supply and/or distribution system.

5. The component as claimed in claim 1 , the component forming a coupling device in which the space is in communication with at least one liquid inlet and at least one liquid outlet, said space housing at least one non-return valve, wherein the space is in communication with at least two liquid outlets.

6. The component as claimed in claim 5 , the component forming a support for the coupling device, said support comprising at least one fastening device suitable for securing an electrical power supply connector of at least one constituent heating element of the supply and/or distribution system.

7. The component as claimed in claim 6 , in which the support and at least one coupling device form a single-piece part.

8. The component as claimed in claim 1 , the component forming a hydraulic connector installed between at least one constituent liquid transport and heating duct of the supply and/or distribution device and a wiper of the wiping system.

9. The component as claimed in claim 8 , in which the hydraulic connector comprises at least one liquid circulation channel forming the space and a contact zone suitable for receiving a heating element, wherein the hydraulic connector comprises at least two liquid circulation channels.

10. A liquid supply and/or distribution system of a wiping installation for a motor vehicle, comprising at least one component, said at least one component including:
a space delimited by a wall in which the liquid spreads, wherein the wall is made of a heat-conducting plastic material; and
a dedicated heat source in physical contact with the wall, wherein the dedicated heat source is a resistive and heating track that extends along an outer face of the wall,
wherein the plastic material is a polyethylene charged with nanofibers and exhibits a thermal diffusivity greater than or equal to 0.00019 m 2 /s.

11. A component of a liquid supply and/or distribution system of a wiping installation for a motor vehicle, comprising:
a space delimited by a wall in which the liquid spreads, wherein the wall is made of a heat-conducting plastic material; and
a heat source in physical contact with the wall, wherein the heat source is a heating element that directly cooperates with a liquid transport and heating tube of the liquid supply and/or distribution system,
wherein the plastic material is a polyethylene charged with nanofibers and exhibits a thermal diffusivity greater than or equal to 0.00019 m 2 /s.

12. A liquid supply and/or distribution system of a wiping installation for a motor vehicle comprising:
at least one component, said at least one component including:
a space delimited by a wall in which the liquid spreads, wherein the wall is made of a heat-conducting plastic material; and
a heat source in physical contact with the wall, wherein the heat source is a heating element that directly cooperates with a liquid transport and heating tube of the liquid supply and/or distribution system,
wherein the plastic material is a polyethylene charged with nanofibers and exhibits a thermal diffusivity greater than or equal to 0.00019 m 2 /s.
