Abstract:
1. A head for a fuel filler pipe of a vehicle, the head comprising an obturating assembly, the obturating assembly further comprising: a body having an aperture for passage to said pipe of a fuel supply spout of predetermined outer diameter; an obturator movable with respect to said body, able to assume an obturating position in which it conceals said passage aperture and a freeing position in which it does not conceal said passage aperture, said obturator flapping rearwardly and outwardly between said obturating position and said freeing position, said obturator being elastically urged towards said obturating position, said obturator being adapted to be driven by said spout from the obturating position to the freeing position when said spout meets the obturator during a thrusting movement of the spout into the head; and an access assembly having a shell through which the spout must pass before reaching the obturator, said shell having a plurality of flexible tabs generally forming an assembly of funnel shape of which the minor diameter is less than said outer diameter of said spout and of which the major diameter is greater than said outer diameter of said spout so that the minor diameter portion of the assembly of funnel shape bears snugly around the spout; wherein the obturator in the obturating position is obliquely disposed with respect to the thrusting movement of the spout, whereby an angular travel of the obturator between the obturating position and the freeing position is reduced; and wherein the shell is disposed in the access assembly with a radial play configured to allow the shell to be appropriately positioned when it cooperates with the spout.
