ABSTRACT:
A closure head for a fuel tank filler pipe allowing automatic opening of a shutter under action of thrust of a nozzle on a device integrated into the top of the filler pipe and closing of the shutter when the nozzle is withdrawn. The locking of the shutter is achieved by a mechanism connected to a bodywork flap such that locking and squashing of a seal are achieved upon the closing of the bodywork flap and the opening of the bodywork flap cannot unlock the shutter without the nozzle additionally being introduced into the system. A method for opening a filler head employs the device.
