Abstract
System for filling a tank comprising a fill pipe and a pipe head comprising an inlet valve and a moveable stopper in the head under the valve, characterized in that the valve comprises a peripheral part and a central part and in that only the peripheral part is coupled to the stopper and capable of causing the opening and/or unlocking of the latter under the pressure of a large-diameter fill nozzle, the central part being moveable with respect to this peripheral part so as to be able to swing under the action of a smaller-diameter fill nozzle, without acting on the stopper, while being connected to this same peripheral part so as to be entrained and swung with it under the pressure of a large-diameter fill nozzle.
