Misfuelling prevention device

摘要

A misfuelling prevention device, a fuel tank and a vehicle are described. The misfuelling prevention device includes an elongated support element arranged inside a tubular element. A first end of the elongated support element is coupled to the tubular element and a second end of the elongated support element and a central section of the elongated support element are arranged such that they are spaced apart from an inner surface of the tubular element. A blocking element is arranged at the second end of the elongated support element, thereby preventing misfuelling.

1. A misfuelling prevention device comprising:
a tubular element configured to be inserted into a filler neck of a fuel tank; an elongated support element arranged inside the tubular element, a first end of the elongated support element being coupled to the tubular element and a second end of the elongated support element and a central section of the elongated support element being arranged such that they are spaced apart from an inner surface of the tubular element; and a blocking element arranged at the second end of the elongated support element, the blocking element being a plate with a surface of the plate being arranged perpendicular to a longitudinal direction of the elongated support element, wherein the plate of the blocking element has a circumference that is a sector of a circle with an arc and a straight side that connects one end of the arc and another end of the arc, and wherein the elongated support element includes a wide plate section and a narrow plate section extending perpendicularly from the wide plate section, thereby forming a T-shaped cross section in a plan perpendicular to the longitudinal direction of the elongated support element, and wherein at the second end of the elongated support element, the wide plate section of the elongated support element is attached to the straight side of the blocking element, and the narrow plate section extends from the wide plate section to a center of the arc of the blocking element.
