FUEL GAS SUPPLY SYSTEM, AND PRESSURE CONTROL METHOD FOR SAME

摘要

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.
