PURPOSE:To enable a large amount of high pressure gas stored in a gas injection part to be instantaneously injected all at once by a method wherein an opening or closing valve tightly fitted in a injection passage at a gas injection part is slightly released up to its releasing start position. CONSTITUTION:An opening or closing valve 54 is closely fitted in an injection passage 16 of a gas injection part A. As the opening or closing valve 5 is slightly released up to a releasing position, a part of the high pressure gas within a pressure increasing storing chamber 20 is flowed into an injection passage 16 and then the opening or closing valve 54 is forcedly pushed all at once with this pressure. With such an arrangement, the opening or closing valve 54 is displaced to its full opened position within a short period of time, a large amount of high pressure gas is flowed into the injection passage 16 all at once and then the gas is injected toward the loading side of the missile. Thus, it is possible to launch the missile with a high injection pressure of high pressure gas at a high speed all at once. |
