Abstract
A closure device for a filler pipe of a tank intended to contain a liquid, the device including a valve that includes a valve body in communication with the pipe and a plug that can be moved in the valve body between a closed position and an open position of the valve. The body of the valve includes an inlet opening closed off by a flap that can be moved between an open position and a closed position, and an outlet opening. The flap is connected to the plug by a coupling such that a thrust exerted on the flap by a tubular end of a nozzle for admitting liquid into the tank causes the flap to tilt into the valve body and the plug to rotate, placing a cylindrical opening in the plug in alignment with inlet and outlet openings in the valve body.
