Abstract

A tank filler tube includes a fill tube line which features, in the tank assembled state, an inlet end further from the tank, which is designed for temporary insertion of the fill nozzle into a closer-to-the-tank insertion region of the fill tube line, and with a closer-to-the-tank transit line end in the tank assembled state, which is designed for transit of liquid in a direction of the liquid transit line leading away from the inlet end, wherein the fill tube line is of multi-part design.
At least one part of the ventilation line is for venting the gas displaced during a filling of a tank into the atmosphere. The fill tube line section featuring the transit line end extends into the insertion region further from the tank and is designed to accommodate at least one outlet end of a fill nozzle during a filling of a tank.

First claim

The invention claimed is:

1. A tank filler tube for a tank of a motor vehicle, comprising:
a fill tube line having an inlet end and a transit end, the inlet end being further from the tank than the transit end, said fill tube line being capable of receiving a fill nozzle into an insertion region of the fill tube line at the inlet end, said transit end being for transit of liquid in a liquid transit direction leading away from the inlet end; and
at least one part of a ventilation line for venting gas displaced during a tank filling into the atmosphere;
wherein the fill tube line is of multi-part design and comprises a plurality of fill tube line sections configured separately from each other and sequentially following each other in the liquid transit direction;
wherein the plurality of fill tube line sections comprises a single-piece fill tube line section including the transit end, which is designed as a single piece, extends into the insertion region, and is designed to accommodate at least one outlet end of the fill nozzle during a filling of the tank;
wherein the tank filler tube entirely extends between the inlet end and the transit end;
wherein the at least one part of the ventilation line has a multi-part design and comprises a plurality of ventilation line segments;
wherein the plurality of ventilation line segments are arranged such that the at least one part of the ventilation line comprises a ventilation line half-dish upstream relative to the liquid transit direction and a ventilation line half-dish downstream relative to the liquid transit direction;
wherein the upstream ventilation line half-dish comprises a wall section extending essentially orthogonally to the liquid transit direction, which provides one of the plurality of fill tube line sections across its wall thickness;
wherein the single-piece fill tube line section including the transit end is a single piece with the downstream ventilation line half-dish;
wherein the single-piece fill tube line section including the transit end passes through the downstream ventilation line half dish;
wherein the wall section of the upstream ventilation line half-dish extending essentially orthogonally to the liquid transit direction, and the single-piece fill tube line section including the transit end, comprise a first border region, are positioned sequentially in the liquid transit direction and are in abutment with each other in the first border region;
wherein the at least one part of the ventilation line includes a ventilation chamber enclosing radially the fill tube line;
wherein the ventilation chamber is penetrated by the fill tube line;
wherein the ventilation chamber is bounded radially outwardly by the upstream ventilation line half-dish and by the downstream ventilation line half-dish; and
wherein the ventilation chamber is bounded radially inwardly by the single-piece fill tube line section.

2. The tank filler tube according to claim 1 ,
wherein at least two fill tube line sections of the plurality of fill tube line sections directly sequential in the liquid transit direction comprise additional border regions, and abut each other in the respective additional border regions.

3. The tank filler tube according to claim 1 ,
wherein the at least one part of the ventilation line comprises a wall section extending essentially orthogonally to the liquid transit direction, which provides a fill tube line section of the plurality of fill tube line sections across its wall thickness.

4. The tank filler tube according to claim 3 ,
wherein a fill tube line section of the plurality of fill tube line sections including the insertion end is designed as a single piece with the wall section of the at least one part of the ventilation line extending essentially orthogonally to the liquid transit direction.

5. The tank filler tube according to claim 1 ,
wherein the ventilation chamber comprises, in a circumferential section, an elongation section extending orthogonally away from the fill tube line relative to the liquid transit direction, wherein the elongation section is separated from a region of the ventilation chamber nearer to the fill tube line by a liquid-permeable separation wall.

6. The tank filler tube according to claim 1 ,
wherein the ventilation chamber includes an interior structure positioned at a distance from the fill tube line in an orthogonal direction to the liquid transit direction and spans at least partially, a ventilation connection in the liquid transit direction.

7. The tank filler tube according to claim 1 ,
wherein a magnet device is disposed at the insertion region of the fill tube line and which surrounds the fill tube line at least partially.

8. The tank filler tube according to claim 7 ,
wherein the magnet device is accommodated at least partly, in a magnet device holder of a fill tube line section of the plurality of fill tube line sections including the insertion end.

9. The tank filler tube according to claim 8
wherein the magnet device holder is bounded by the wall section of the at least one part of the ventilation line extending essentially orthogonally to the liquid transit direction.

10. A motor vehicle, comprising the tank filler tube according to claim 1 .

11. The tank filler tube according to claim 1 , wherein the plurality of ventilation line segments are arranged sequentially in the liquid transit direction.

12. The tank filler tube according to claim 1 , wherein all fill tube line sections of the plurality of fill tube line sections directly sequential in the liquid transit direction comprise respective additional border regions and abut each other in the respective additional border regions.

13. The tank filler tube according to claim 1 , wherein between the fill tube line and ventilation chamber there is a ventilation connection.

14. The tank filler tube according to claim 1 , wherein the ventilation chamber includes a baffle plate positioned at a distance from the fill tube line in an orthogonal direction to the liquid transit direction and completely spanning a ventilation connection in the liquid transit direction.

15. The tank filler tube according to claim 7 , wherein the insertion region surrounds the fill tube line entirely.

16. The tank filler tube according to claim 7 , wherein the magnet device is accommodated entirely in a magnet device holder of a fill tube line section featuring the insertion end.
