Au brevet français 8216257, on décrit déjà un dispositif d'alimentation en carburant gazeux d'un moteur à combustion interne comprenant une vanne commandée par la pédale d'accélération et destinée à The present invention relates to valves and, more particularly, to those intended to be used in gaseous fuel supply devices, especially liquefied petroleum gas, carburetor (an internal combustion engine usually operating In the French patent 8216257, there is already described a device for supplying gaseous fuel to an internal combustion engine comprising a valve controlled by the accelerator pedal and intended for

That's why we give up,
