Abstract

The invention relates to an insert element 13 for inserting into the filler neck 10 of a tank suitable for filling with urea at a filling station by means of a pump nozzle 12. The insert element 13 comprises a cover element 24 with an opening having an inner diameter that is smaller than the outer diameter of a standard pump nozzle spout 12 for Diesel fuel, and support means for mounting the cover element 24 to substantially the plane of opening of the filler neck 10.

Claims

1. An insert element (13) for inserting into the filler neck (10) of a tank suitable for filling with urea at a filling station by means of a pump nozzle (12), said insert element (13) comprising

a cover element (24) with an opening having an inner diameter that is smaller than the outer diameter of a pump nozzle spout (12) for Diesel fuel,

and support means for positionally securing the cover element (24) to substantially the plane of opening of the filler neck (10).

2. The insert element (13) as set forth in claim 1,

characterized in that said insert element (13) comprises a reducer (16) which can be shift-mounted in the filler neck (10) of the tank.

3. The insert element (13) as set forth in claim 1,

characterized in that a magnet (19) can be mounted to interact with a magnetic switch included in a urea pump nozzle (12).

4. The insert element (13) as set forth in claim 2,

characterized in that said reducer (16) is male screw-threaded for screwing the reducer into the filler neck (10) of the tank.

5. The insert element (13) as set forth in claim 2,

characterized in that said reducer (16) features rim tabs (36) forming together with the cap locking element (42) of the filler neck (10) a bayonet lock.

6. The insert element (13) as set forth in claim 1,

characterized in that said cover element (24) comprises at its filler opening end a male coupling (30), and the insert element includes furthermore a female-threaded cap (33) for screwing onto the male coupling to close off the insert element (13).

7. The insert element (13) as set forth in claim 6,

characterized in that said screw thread of the cap (33) or the complementary screw thread of the male coupling (30) has an ascending thread to create a resistance to the cap becoming loose on the male coupling, i.e. the cap only being releasable by an intentional manual turning.

8. The insert element (13) as set forth in claim 2,

characterized in that said reducer (16) features at its filler opening end a bayonet recess, and a cap for the insert element (13) is provided with tabs on the underside which to form a bayonet lock between the cap and the reducer engage the bayonet recess.

9. The insert element (13) as set forth in claim 1,

characterized in that axial longitudinal recesses are provided in the inner wall of the reducer (16) so that air can flow through between a urea pump nozzle (12) inserted in the insert element and the reducer (16).

10. The insert element (13) as set forth in claim 8,

characterized in that the insert element features a special tab wrench engineered to mate with the cited recesses (39) or bayonet recess of the cover element to rotationally lock the insert element (13) to a filler neck.

11. The insert element (13) as set forth in claim 2,

characterized in that is rendered theft-proof by means of a screw to lock the insert element (13) to the filler neck (12) by screwing the screw into a tapping provided transversely to the centerline of the reducer (16).

12. The insert element as set forth in claim 1,

characterized in that said cover element (24) comprises a lid (44) pivoted to cover its opening.

13. The insert element as set forth in claim 12,

characterized in that at least one discharge passage (45) is provided via which with pivoted lid (44) closed any fluid in contact therewith can flow off.

14. A motor vehicle tank for urea, the filler neck of which is fitted with an insert element (13) as set forth in claim 1.

15. A jerrycan featuring a filler opening and a lockable, removable cap for closing off the opening, through which with the aid of the pump nozzle (12) in the filling station the opened jerrycan can be filled with urea,

characterized in that said filler opening has a rim located in the plane of the opening, the inner diameter of which is smaller than the outer diameter of the pump nozzle spout as standardized for Diesel fuel.

16. The jerrycan as set forth in claim 15,

characterized in that arranged beneath the rim of the filler opening is a magnet interacting with a magnetic switch provided in the pump nozzle.

17. The jerrycan as set forth in claim 15,

characterized in that said cover element (24) comprises a lid (44) pivoted to cover its opening.

18. The jerrycan as set forth in claim 17,

characterized in that at least one discharge passage (45) is provided via which, with the pivoted lid (44) closed, any fluid in contact therewith can flow off.
