Embodiment Construction

[0021] figure 1 Shown is a tank filling neck 1 for a motor vehicle comprising a plastic tube 2, a filling head 3 made of metal and surrounding the plastic tube 2 at its end, and made of an elastomer, in particular rubber And a first seal 4 arranged on the periphery between the plastic tube 2 and the filling head 3 . In this example, the filling head 3 is formed as a sheet metal shaped part, but in principle it can also be produced in a different way. Furthermore, the tank filling neck 1 comprises a first support ring 5 , which is arranged opposite the first seal 4 with respect to the plastic tube 2 and has a greater wall thickness than the filling head 3 . The first support ring 5 can consist, for example, of metal or plastic, in particular fiber-reinforced plastic.

[0022] The fixing of the filling head 3 on the plastic tube 2 is stabilized by using a first support ring 5 . Due to the fact that the wall thickness of the first support ring 5 is greater than that of the fi...

Abstract

Described is a tank filling neck (1) for a motor vehicle, which includes a plastic tube (2), a filling head (3) made of metal and surrounding the plastic tube (2) at its end. , and a first seal (4) made of elastomer and arranged on the periphery between the plastic tube (2) and the filling head (3). Furthermore, the tank filling neck (1) also includes a first support ring (5), which is arranged opposite the first seal (4) with respect to the plastic tube (2) and has a wall thickness greater than that of the filling head (3) . Finally, a motor vehicle is also described, which includes a tank filling neck (1) of the type described.

Description

technical field [0001] The invention relates to a tank filling neck for a motor vehicle, comprising a plastic tube, a filling head made of metal and surrounding the plastic tube at the end of the plastic tube, and a filling head made of elastomer and arranged between the plastic tube and the filling head The first seal on the perimeter between. The invention also relates to a motor vehicle with such a filler neck. Background technique [0002] Such filling necks and such motor vehicles are basically known from the prior art. For example, DE 30 27 002 A1 discloses a tank filling neck arrangement for this purpose and in particular for motor vehicles, which has a concentrically arranged filling neck made of plastic and a closing base made of metal. The fill neck is surrounded by a closed base with pressure. For this purpose, the filling neck is supported by an inner support sleeve at the base of the closure. Furthermore, an annular seal acting between the two parts is arran...
