Title
(EN) FUEL GAS SUPPLY SYSTEM, AND PRESSURE CONTROL METHOD FOR SAME
(FR) SYSTÈME D'ALIMENTATION EN GAZ COMBUSTIBLE ET PROCÉDÉ DE COMMANDE DE LA PRESSION POUR CE SYSTÈME

Abstract
(EN)
This fuel gas supply system is configured such that a fuel gas in a high-pressure tank is supplied to a fuel gas consuming apparatus through a supply path. The supply path is branched into first and second flow channels, and then the flow channels are joined together to be one joined flow channel. The first flow channel is provided with an electromagnetic on-off valve that opens and closes the first flow channel, and the second flow channel is provided with an electromagnetic pressure regulating valve that regulates pressure of the fuel gas flowing in the second flow channel. The electromagnetic pressure regulating valve is configured such that the Cv value thereof is smaller than the Cv value of the electromagnetic on-off valve.
(FR)
L'invention concerne un système d'alimentation en gaz combustible conçu de sorte qu'un gaz combustible contenu dans un réservoir à haute pression soit acheminé à un appareil consommant un gaz combustible par un trajet d'acheminement. Le trajet d'acheminement est divisé en des premier et second canaux d'écoulement et les canaux d'écoulement sont ensuite réunis pour constituer un seul canal d'écoulement réuni. Le premier canal d'écoulement est équipé d'une vanne marche-arrêt électromagnétique qui ouvre et ferme le premier canal d'écoulement, et le second canal d'écoulement est équipé d'une vanne de régulation de la pression électromagnétique qui règle la pression du gaz combustible passant dans le second canal d'écoulement. La vanne de régulation de la pression électromagnétique est conçue de sorte que sa valeur Cv soit plus petite que la valeur Cv de la vanne électromagnétique marche-arrêt.
(JA)
 燃料ガス供給システムは、供給通路を介して高圧タンクの燃料ガスを燃料ガス消費器に供給するように構成されており、供給通路は、第1及び第2流路に分岐し、その後1つの合流流路に合流している。第1流路には、そこを開閉する電磁式開閉弁が設けられており、第2流路には、そこを流れる燃料ガスを調圧する電磁式調圧弁が設けられている。そして、電磁式調圧弁は、そのCv値が電磁式開閉弁のCv値よりも小さくなるように構成されている。
