Beschreibung
Zusammenfassung:	The present invention provides a pressure control method for a high-pressure regulator to prevent internal leak, and the high-pressure shut-off valve so as to minimize an internal leak, due to high-pressure gas remaining in a high-pressure fuel line when a valve of a gas storage tank is shut off, caused by a pressure difference between a front end portion and a rear end portion of the high-pressure regulator introducing or discharging high-pressure gas. Accordingly, the convenience for connecting work is provided, the high safety is ensured, and the high-pressure regulator is used with the high reliability.
