Abstract

A motor vehicle operating fluid container is made of thermoplastic. The container is composed of two shells forming a substantially closed hollow body. A first shell forms an upper base of the container, and a second shell forms a lower base of the container. The container includes at least one line which is designed as an integral part of a container wall over at least one sub-length, where the line is designed as a channel which runs in the container wall over said sub-length. The channel has an open trough-shaped profiled cross-section which forms a part of the line cross-section, and the channel is closed by at least one cover which complements the trough-shaped profiled cross-section so as to form a closed cross-section.

First claim

The invention claimed is:

1. An operating fluid container for a motor vehicle, made of thermoplastic material, comprising:
two shells that form a substantially closed hollow body, wherein a first shell forms a top of the container and a second shell forms a bottom of the container,
at least one line formed as an integral component part of a container wall over at least a partial length, wherein the line is formed as a channel in the container wall, wherein the channel has an open, trough-shaped profile in cross section, and extends from a first connection point in the top of the container to a second connection point at an outer edge of the top, wherein the first connection point is arranged preferably approximately in a centroid of an area of the top, and
at least one cover that closes the channel, wherein the cover complements the trough-shaped profile.

2. The operating fluid container as claimed in claim 1 , wherein the cover is welded to the container wall.

3. The operating fluid container as claimed in claim 1 , wherein the channel extends in the top of the container.

4. The operating fluid container as claimed in claim 1 , wherein the second connection point is a connection fitting integrally formed on the top.

5. The operating fluid container as claimed in claim 1 , wherein the line is a ventilation line of the container.

6. The operating fluid container as claimed in claim 1 , wherein the line extends between a filling ventilation valve and the second connection point.

7. The operating fluid container as claimed in claim 2 , wherein the container wall has thickened portions, which form an edge-side surround of the channel.

8. The operating fluid container as claimed in claim 1 , wherein the cover has an integrally formed valve housing receptacle.

9. The operating fluid container as claimed in claim 1 , wherein the cover is formed from an electrically conductive thermoplastic material.

10. The operating fluid container as claimed in claim 1 , wherein the cover is an electrical heating element.

11. The operating fluid container as claimed in claim 1 , wherein the cover has integrally formed baffle elements as a droplet separator.

12. The operating fluid container as claimed in claim 1 , wherein the cover has at least one integrally formed connection fitting.

13. The operating fluid container as claimed in claim 1 , wherein the cover comprises an electrical heating element.
