A filler neck assembly includes a supporting part designed to be fixed at the inlet of a liquid tank positioned on a motor vehicle and said supporting part having a central through hole mainly formed about a central axis. The filler neck assembly also includes a tubular part that is positioned in said central through hole and said tubular part having a longitudinal axis. The filler neck assembly further includes a first abutment area and a second abutment area attached to one part which is selected between the supporting part and the tubular part, and a contacting area attached to the other part which is selected between the tubular part and the supporting part such that said contacting area can cooperate with one or other of the first and second abutment areas. The first and second abutment areas and the contacting area are arranged so that the cooperation of the contacting area with the first abutment area defines a first angular position of the tubular part with respect to said supporting part and the cooperation of the contacting area with the second abutment area defines a second angular position of the tubular part with respect to said supporting part.

1. A filler neck assembly comprising: a supporting part designed to be fixed at an inlet of a liquid tank positioned on a motor vehicle and the supporting part having a central through hole mainly formed about a central axis,a tubular part that is positioned in the central through hole and the tubular part having a longitudinal axis, wherein the filler neck assembly further comprisesat least a first abutment area and a second abutment area attached to one part which is selected between the supporting part and the tubular part,at least one contacting area attached to another part which is selected between the tubular part and the supporting part such that the contacting area can cooperate with one or other of the first and second abutment areas,wherein the first and second abutment areas and the contacting area are arranged so that the cooperation of the contacting area with the first abutment area defines a first angular position of the tubular part with respect to the supporting part and cooperation of the contacting area with the second abutment area defines a second angular position of the tubular part with respect to the supporting part. 2. The filler neck assembly according to claim 1, wherein first and second abutment areas and the contacting area are arranged such that in the first angular position the longitudinal axis is merged with the central axis or inclined with respect to the central axis according to a first angle and such that in the second angular position the longitudinal axis is inclined with respect to the central axis according to a second angle. 3. The filler neck assembly according to claim 2, wherein first and second abutment areas are arranged such that in the first angular position the longitudinal axis is merged with the central axis or inclined with respect to the central axis with a first angle less than 15° and in the second angular position the longitudinal axis is inclined with respect to the central axis with a second angle comprised between 5 and 65° preferably between 10 and 35°. 4. The filler neck assembly according to claim 1, wherein the at least first and second abutment areas are formed in the central through hole by respective first and second annular grooves and the at least one contacting area is formed by at least one annular rib that protrudes around the tubular part and that is designed to engage one or other of the first and second annular grooves. 5. The filler neck assembly according to claim 4, wherein the first annular groove lies on a first plane that is inclined with respect to the central axis according to a first inclination and the second annular groove lies on a second plane that is inclined with respect to the central axis according to a second inclination. 6. The filler neck assembly according to claim 5, wherein the first plane is substantially perpendicular to the central axis and the second plane is inclined with respect to the central axis with an angle comprised between 95° and 155°, and preferably with an angle comprised between 100° and 125°. 7. The filler neck assembly according to claim 4, wherein the annular rib lies on a plane that is perpendicular to the longitudinal axis of the tubular part. 8. The filler neck assembly according to claim 7, wherein an annular groove is formed in the annular rib and a seal ring is positioned in the annular groove of the annular rib. 9. The filler neck assembly according to claim 8, wherein the first and second annular grooves, the annular rib, the annular groove formed in the annular rib and the seal ring are sized such that, when the tubular part is inserted in the central through hole of the annular part, the seal ring is radially pressed against the bottom surface of the first or second annular groove in which the annular rib is engaged. 10. The filler neck assembly according to claim 4, wherein the annular rib according to claim 4 is a first annular rib and the tubular part is provided with at least a second annular rib protruding around the tubular part, parallel to the first annular rib and located at distance from the first annular rib. 11. The filler neck assembly according to claim 10, wherein the second annular rib is designed to engage one or other of the first and second annular grooves to define with the first annular rib third and fourth positions of the tubular part with respect to the supporting part. 12. The filler neck assembly according to claim 1, wherein the central through hole is formed by the intersection of a first cylinder and a second cylinder having a circular cross-section, having approximately the same diameter and arranged to each other so that their respective axes of revolution intersect together with an angle of intersection (β) comprised between 1 and 45°, preferably between 5 and 25°. 13. The filler neck assembly according to claim 4, wherein the first annular groove is formed in the first cylinder and the second annular groove is formed second cylinder. 14. The filler neck assembly according to claim 12, wherein the axis of revolution of the first cylinder is merged with the central axis. 15. The filler neck assembly according to claim 12, wherein the first and the second cylinders have a diameter that is approximately the same as the outside diameter of the tubular part. 16. The filler neck assembly according to claim 1, wherein the at least one contacting area is formed in the central through hole by an annular groove and the at least first and second abutment areas are formed by respective first and second annular ribs that protrude around the tubular part and that are designed so that in the first angular position the first annular rib engages the annular groove and in the second annular position the second annular rib engages the annular groove. 17. The filler neck assembly according to claim 1, wherein the tubular part includes a tubular sleeve arranged to slide in the tubular part, along the longitudinal axis, between a retracted position where the tubular sleeve is partially or totally retracted in the tubular part and an extended position where the tubular sleeve extends outside from the tubular part. 18.
