ABSTRACT:
An on-off valve mounted in a high pressurized gas container, which has a holding portion for holding a flow amount controlling member in a path formed in an upper stream side of the body of the valve, and in which a flow amount controlling member is movably held. In the flow amount controlling member, an orifice is formed. When the valve moves into an opening position, a high pressurized oxygen gas is flowed into a valve chamber by gas pressure, the flow amount controlling member moves and closes the path. At this time, the gas flow amount is restricted by the orifice, so that the pressurizing speed of the gas pressure at the down stream side of the orifice becomes slow and then heat generation due to the adiabatic compression is reduced.
