<p>PURPOSE:To effectively utilize the pressure of carbonic acid gas from a carbonic acid gas bomb, as a power source in a place where no electrical power, etc. is available by introducing fluid discharged from the carbonic acid gas bomb into a secondary pressure chamber, and then by introducing the fluid into a fluid- operable actuating apparatus. CONSTITUTION:When the front end of a carbonic acid gas bomb 6 is screwed into a bomb screwing connection 47, a seal-opening needle 41 opens the bomb 6 so that carbonic acid gas is discharged. The carbonic acid gas flows through a passage 41 in the seal opening needle 41, the gap between a through-hole 28 and a valve rod 30, a pressurizing chamber 26 and a passage 27 in a movable member 24, and pushes a valve ball 13 in a check valve 10 toward a secondary pressure chamber 2. Further, the gas flows through a passage 15 in the secondary pressure chamber 2 into the inside of the secondary pressure chamber 2. The carbonic acid gas in the secondary pressure chamber 2 is a gas whose pressure is lowered to a value which is lower than that of the gas bomb 6, and therefore, may be fed into a fluid operable actuating apparatus 8.</p> |
