Abstract

In order to improve and in particular to more economically manufacture and/or assemble and/or maintain a sump device comprising a sump body particularly for an oil supply in a commercial motor vehicle having a pipe unit comprising a pipe body wherein the sump body is an injection moulded part of plastics material, it is proposed that the pipe unit be arranged on the sump body with play.

First claim

The invention claimed is:

1. Sump device comprising a sump body, with a pipe unit comprising a pipe body wherein the sump body is an injection moulded part of plastics material, wherein the pipe unit is supported by the sump body with play at an outlet end of the of the pipe unit, and wherein an interior space of the pipe body extends between opposed ends of the pipe body, the interior space of the pipe body defined by the pipe body alone, thereby spaced away and separate from the sump body, and wherein the outlet end of the pipe unit is arranged with play at least partially in the direction of a depth direction of the sump body.

2. The sump device in accordance with claim 1 , wherein the pipe unit is held with play.

3. The sump device in accordance with claim 1 , wherein there is provided a nominal position for the pipe unit and the pipe unit is arranged with play in this nominal position.

4. The sump device in accordance with claim 1 , wherein the pipe unit is arranged with play at least partially in at least one direction running at least approximately perpendicularly to the depth direction of the sump body.

5. The sump device in accordance with claim 1 , wherein a holding device holds the pipe unit with play.

6. The sump device in accordance with claim 5 , wherein the holding device has at least two boundary surfaces between which the pipe unit is arranged with play.

7. The sump device in accordance with claim 6 , wherein the boundary surfaces, with regard to a nominal location of a respective corresponding contact surface of the pipe unit which it adopts when the pipe unit is positioned in the nominal position, are arranged at a corresponding spacing.

8. The sump device in accordance with claim 7 , wherein the respective spacing corresponds to a corresponding maximally permitted deflection of the pipe unit from the nominal position.

9. The sump device in accordance with claim 1 , wherein the pipe unit comprises at least one locating element which is arranged on an outer surface of the pipe body.

10. The sump device in accordance with claim 1 , wherein the pipe body is arranged at least partially between two boundary surfaces.

11. The sump device in accordance with claim 1 , wherein an engagement body of a locating element engages in an intermediate space of a holding element.

12. The sump device in accordance with claim 11 , wherein the intermediate space is bounded by at least two boundary surfaces.

13. The sump device in accordance with claim 11 , wherein the intermediate space of at least one holding element is opened in the direction of a withdrawal direction and/or in the direction of the depth direction.

14. The sump device in accordance with claim 11 , wherein the intermediate space of at least one holding element does not comprise an undercut taken with respect to the withdrawal direction.

15. The sump device in accordance with claim 11 , wherein the intermediate space comprises at least two branches.

16. The sump device in accordance with claim 15 , wherein the at least two branches are each bounded by at least two respective boundary surfaces.

17. The sump device in accordance with claim 1 , wherein at least one locating element latches with a holding element.

18. The sump device of claim 1 , wherein the sump device is configured for an oil supply in a commercial motor vehicle.

19. Sump device comprising a sump body, with a pipe unit comprising a pipe body wherein the sump body is an injection moulded part of plastics material, wherein the pipe unit is arranged on the sump body with play, wherein a holding device holds the pipe unit with play, wherein the holding device comprises a plurality of holding elements for holding the pipe unit with play, the holding elements being supported by the sump body and spaced apart along a longitudinal direction of the pipe unit, and wherein the holding elements comprise a first holding element proximate a first end part of the pipe body, a second holding element proximate a second end part of the pipe body and a third holding element intermediate of the first and second holding elements.

20. The sump device of claim 19 , wherein the outlet end of the pipe unit is arranged with play at least partially in the direction of a depth direction of the sump body.

21. The sump device of claim 19 , wherein the first, second and third holding elements each separately hold the pipe unit with play.

22. Sump device comprising a sump body, with a pipe unit comprising a pipe body, wherein an interior space of the pipe body extends between opposed ends of the pipe body, the interior space of the pipe body defined by the pipe body alone, thereby spaced away and separate from the sump body, wherein the sump body is an injection moulded part of plastics material, wherein the pipe unit is arranged on the sump body with play, wherein a holding device holds the pipe unit with play, wherein the holding device is supported by the sump body and holds the pipe unit in a releasable manner, and wherein the outlet end of the pipe unit is arranged with play at least partially in the direction of a depth direction of the sump body.

23. Sump device comprising a sump body, with a pipe unit comprising a pipe body wherein the sump body is an injection moulded part of plastics material, the sump body including a sump base and a sump opening above the sump base, wherein the pipe unit is supported by the sump body with play proximate the sump opening, the pipe body extending between a first end oriented toward the sump opening and a second end, the second end enclosing an interior space that is spaced above and separate from the sump base for sucking up oil, and wherein the outlet end of the pipe unit is arranged with play at least partially in the direction of a depth direction of the sump body.
