- the high-pressure source gas filled in the second chamber 182 formed under the lower plunger 120 acts on the lower portion of the lower plunger 120 to form the first chamber 164 .
- a pressure difference is generated between the and the second chamber 182 , and the lower plunger 120 is raised by the pressure difference to open the outlet 134 of the valve seat 104 .
- the high-pressure fluid acting on the lower part of the lower plunger 120 acts on the upper part of the lower plunger 120 so that the high-pressure fluid acts on the entire lower plunger 120 and the upper plunger 112, and the outlet 134 is opened and the source gas stored in the high-pressure container is supplied to the gas using unit by communicating with the fourth flow path 36 and the third flow path 34 .
- a valve assembly is installed in the high-pressure container in which the source gas is stored to control the flow of the source gas when the source gas is filled into the high-pressure container, and to control the flow of the source gas when the source gas stored in the high-pressure container is supplied to the user.
