Abstract
A fuel gas supplying and filling system for a fuel gas consuming unit, capable of using a supply passage in both filling and supplying operations and improving the airtightness and reliability of a fill passage. A high-pressure tank and a fuel gas consuming unit are connected to each other by a supply passage, and an electromagnetic pressure regulating valve is provided on the supply passage. An electromagnetic on-off valve is provided between the electromagnetic pressure regulating valve and the high-pressure tank. A fill passage is connected to a portion of the supply passage, the portion being located between the electromagnetic pressure regulating valve and the electromagnetic on-off valve. The fill passage is configured such that the high-pressure fuel gas can be supplied through a filling opening. When the high-pressure fuel gas is introduced to a downstream side of the electromagnetic on-off valve, the electromagnetic on-off valve opens the supply passage.
