〔産業上の利用分野〕
本発明は人工衛星、ロケット等の種々の分離・展開の開
始機構として用いられる爆管（スクイブ）に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a squib used as an initiation mechanism for the separation and deployment of various types of artificial satellites, rockets, etc.
従来、この種の爆管は、電力を用いてヒータを加熱し、
火薬に点火し、そのガス圧を用いて仕事をさせるもので
あった。Conventionally, this type of blast tube uses electric power to heat the heater,
It involved igniting gunpowder and using the gas pressure to do work.
上述した従来の爆管は、火薬を用いているため、その取
扱いや輸送には制約も多く、安全上の問題があるという
欠点がある。Since the above-mentioned conventional explosive tube uses gunpowder, there are many restrictions on its handling and transportation, and there are drawbacks such as safety issues.
本発明の爆管は、密封型のケースと、該ケース内に可動
自在に保持され一端が前記ケースの外部に突出するピス
トンと、前記ケース内に設けられたし−タと、該ヒータ
の加熱により沸騰・気化しその圧力により前記ピストン
を可動させる液体とを備えている。The blast tube of the present invention includes a sealed case, a piston movably held in the case and having one end protruding outside the case, a heater provided in the case, and a heater for heating. The liquid boils and vaporizes, and the pressure of the liquid causes the piston to move.
また本発明の爆管は、前記ピストンをその可動方向に付
勢するばねを備えている。Further, the blast tube of the present invention includes a spring that biases the piston in its movable direction.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図ないし第４図は本発明のそれぞれ第１ないし第４
の実施例の縦断面図である。1 to 4 are the first to fourth diagrams of the present invention, respectively.
FIG.
第１図に示す第１の実施例において、１はケース、２は
ピストン、３はヒータ、４は電気配線である。電気配線
４に通電することによりヒータ３が加熱され、液体５が
沸騰する。液体５の中で生成された気体はＯリング６に
より外部へ逃げられないため、しだいに圧力を高めピス
トン２を押す。In the first embodiment shown in FIG. 1, 1 is a case, 2 is a piston, 3 is a heater, and 4 is electrical wiring. By energizing the electric wiring 4, the heater 3 is heated and the liquid 5 is boiled. Since the gas generated in the liquid 5 cannot escape to the outside due to the O-ring 6, the pressure is gradually increased and the piston 2 is pushed.
初期はビン７によりピストン２は押えられいるためピス
トン２は動けないが、液体５の圧力がある値になるとビ
ン７はその圧゛にたえきれずに破壊し、ピストン２は矢
印Ａ方向へ急速に移動する。このピストン２の力で種々
の仕事をすることができる。Initially, the piston 2 is held down by the bottle 7, so the piston 2 cannot move, but when the pressure of the liquid 5 reaches a certain value, the bottle 7 cannot withstand the pressure and breaks, and the piston 2 rapidly moves in the direction of arrow A. Move to. The force of this piston 2 can perform various tasks.
なお、ピストン２の強力なエネルギーはクツション８に
より吸収され、ケース１及びピストン２は破壊すること
なく、気体をＯリング６により封じ込めたまま停止する
。Note that the strong energy of the piston 2 is absorbed by the cushion 8, and the case 1 and the piston 2 are stopped without being destroyed, with the gas being confined by the O-ring 6.
第２図に示す第２の実施例は、第１の実施例と路間−の
構成で作動時にピストン２が引き込まれる方向（矢印Ｂ

方により選ぶことができる。The second embodiment shown in FIG.
direction). That is, the first embodiment operates in the direction in which the piston 2 is pushed out, and the second embodiment operates in the direction in which the piston 2 is retracted. Both can be selected depending on usage.
第３図に示す第３の実施例は第１の実施例の応用であり
、ばね９を追加している。ばね９はピストン２を押し出
す方向（矢印Ｃ方向）に常に働いており、作動後、気体
が再び液化して負圧になり、ピストン２が作動前の方向
（矢印Ｃと逆方向）に動くことを禁止している。The third embodiment shown in FIG. 3 is an application of the first embodiment, with the addition of a spring 9. The spring 9 always works in the direction of pushing out the piston 2 (in the direction of arrow C), and after activation, the gas liquefies again and becomes negative pressure, causing the piston 2 to move in the direction before activation (in the opposite direction to arrow C). is prohibited.
第４図に示す第４の実施例は第２の実施例の応用であり
、原理は第３の実施例と同じで、ばね９はピストン２を
引き込む方向く矢印り方向）に常に働いている。The fourth embodiment shown in FIG. 4 is an application of the second embodiment, and the principle is the same as that of the third embodiment, in which the spring 9 is always working in the direction of drawing the piston 2 (in the direction of the arrow). .
なお液体５は環境、物性、使用圧等から選定するが、例
えば水を用いれば火薬に比べ安全性を格段に向上するこ
とが可能である。The liquid 5 is selected based on the environment, physical properties, operating pressure, etc., but if water is used, for example, safety can be significantly improved compared to gunpowder.
以上説明したように本発明は、液体を加熱・気化しその
圧力によりピストンを動かすように構成することにより
、従来火薬を用いていた仕事を安全に行うことができる
効果がある。As explained above, the present invention has the effect of safely performing work that conventionally required explosives by heating and vaporizing a liquid and using the resulting pressure to move a piston.
