Beschreibung
Zusammenfassung:	Disclosed is a sealing structure used in a high-pressure regulator for decompressing fuel supply pressure of the vehicle into low pressure, which includes: a body for providing the low pressure at a lower end of a spool through a balance groove communicating with an outlet port; and a sealing member accommodated on the body to maintain the low pressure of the spool, and including an auxiliary part for enhancing airtightness at a spring-energized seal. Accordingly, operation reliability is increased by minimizing the pressure change at the outlet according to the pressure change at the inlet, based on the energized seal during the process of decompressing the high-pressure hydrogen fuel in the hydrogen fuel cell electric vehicle.
