〔産業上の利用分野〕
本発明は、液体、気体、粉体用のシール材に関し、例え
ば液酸／液水ロケットエンジンの噴射器と燃焼室の間に
適用されるシール材、その他シールを必要とするあらゆ
る製品に適用されるシール材に関し、シール面間隙が時
間とともに変化する場合のシール性能の向上とシール部
機構の簡略化を可能としたシール材に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sealing material for liquids, gases, and powders, and is applied, for example, between an injector and a combustion chamber of a liquid acid/liquid water rocket engine. This invention relates to sealing materials that can be applied to sealing materials and other products that require sealing, and that can improve sealing performance when the seal surface gap changes over time and simplify the sealing mechanism.
シール材は、その用途によって金属、ゴム、アスベスト
、テフロン等種々の材料がオリ用されているが、時間と
ともにシール面圧やシール面間隙が変化する場合には、
特に金属シール材については材料自体の弾性回復（ある
いは回復力）によってシール性能を維持することは不可
能である。Various materials are used for sealing materials, such as metal, rubber, asbestos, and Teflon, depending on the application, but if the sealing surface pressure or sealing surface gap changes over time,
In particular, with respect to metal sealing materials, it is impossible to maintain sealing performance due to the elastic recovery (or recovery force) of the material itself.
また一般にはバネや油圧機構を組み込んでシール面圧や
シール面間隙の変化に対応しているが、シール部周辺構
造が複雑化するとともに、これらの機構をうまく組込み
得るシール部構造は限られている。In addition, springs and hydraulic mechanisms are generally incorporated to cope with changes in seal surface pressure and seal surface gap, but this increases the complexity of the structure around the seal and limits the number of seal structures that can successfully incorporate these mechanisms. There is.
上述のように、従来のシール材及びシール技術では、シ
ール面圧やシール面間隙が時間とともに変化する場合、
シール材の弾性回復（あるいは回復力）が少いため、安
定したシール性能が得られないという問題点がある。As mentioned above, with conventional sealing materials and sealing technologies, if the seal surface pressure or seal surface gap changes over time,
Since the sealing material has little elastic recovery (or recovery force), there is a problem in that stable sealing performance cannot be obtained.
また、バネ等によるシール材駆動後宿を組込んでシール
面間隙の変化に対して血圧を一定に保つ場合においても
、シール機構がり雑になるとともに、適用可能な部品構
造も限らｔている等の問題点がある。Furthermore, even if a spring or the like is incorporated to drive the sealing material to keep the blood pressure constant despite changes in the sealing surface gap, the sealing mechanism becomes complicated and the applicable parts structures are also limited. There is a problem with this.
本発明は、上記問題点を、超弾性材料の使用によシ解決
するものである。The present invention solves the above problems by using a superelastic material.
すなわち本発明は、超弾性材料により製造してなる液体

is about 0.2%, but the superelastic material used in the present invention is a material that causes elastic deformation of 5 to 10% under specific temperature conditions. We mourn its function as a material.
また、本発明に使用する超弾性材料の変形特性は、通常
のバネとは異な夛、復元力がひずみ量に依存せずにほぼ
一定となる。Further, the deformation characteristics of the superelastic material used in the present invention are different from those of ordinary springs, and the restoring force is almost constant regardless of the amount of strain.
従って、シール面圧負荷ｅ構もしくはシール材そのもの

時間的に変化してもその変位にｍ座に追従し、更にシー
ル面圧も常に一足に維持し得るため、安定したシール性
能が得られるとともに、シール機構が簡略化できる。Therefore, in the present invention, which uses a superelastic material as the seal surface pressure load structure or the seal material itself, even if the seal surface gap changes over time, it follows the displacement of the seal surface gap over time, and furthermore, the seal surface pressure always remains constant. Therefore, stable sealing performance can be obtained and the sealing mechanism can be simplified.

２図中、第１図と同一符号は第１図と同一部を示す。As shown in (b), if the sealing surface gap is wide, sufficient sealing performance cannot be maintained. - In the present invention, if the sealing tube is made of superelastic material, as shown in Fig. 2 (Bl
The tube shown in (a) is shown in Fig. 2 (B) (as shown in bJ, the tube 4 elastically changes its shape in response to changes in the sealing surface gap, and always generates a nearly constant sealing surface pressure. Therefore, it is possible to improve the sealing performance.In addition, in FIG. 2, the same reference numerals as in FIG. 1 indicate the same parts as in FIG.
ここで、本発明における超弾性材料の記憶形状は、最大
シール面間隙に対してもシール面圧が働くように設定さ

萱た本発明において、超弾性材料を単独でシール材とし

シール機構の簡略化を計ることができる。In order to seal areas where the seal surface gap changes, it is not possible to obtain sufficient sealing performance with ordinary sealing materials alone, so it is necessary to use springs, hydraulic pressure, etc. to follow the displacement and apply a constant sealing pressure. A mechanism is required. In contrast, the present invention is characterized by using a superelastic material as the seal material (or seal surface pressure loading mechanism), which improves the sealing performance in areas where the seal surface pressure and seal surface gap change and simplifies the seal mechanism. can be measured.
