Description
圧力容器は、通常、例えば、水素、酸素、天然ガス、窒素、プロパン、メタン、及び、他の燃料の貯蔵などの様々な流体を加圧された状態で収容するために用いられる。適切な容器シェル材料は、熱硬化性または熱可塑性樹脂により互いに接着された、巻き付けられた、繊維ガラスフィラメントまたは他の合成フィラメント、の積層を含む。ポリマーまたは他の非金属の弾力性のあるライナまたはブラダが、多くの場合、複合材シェル内に配置されて容器を密閉し、且つ、内部流体が複合材料に接触することを防止する。容器の複合材構造は、重量の軽さ、並びに、腐食、疲労及び破局的な破損に対する耐性などの、多数の有利な点をもたらす。これらの特性は、少なくとも一部において、通常、圧力容器の製造において、主要な力の方向に配向される、強化繊維またはフィラメントの高比強度によるものである。
[概要]

項目1.内室を備える圧力容器であって、
上記圧力容器は、
外側シェルと、
上記外側シェルに嵌合されたボスであって、
上記内室と当該圧力容器の外部との間に延在するポートと、
上記ポートから放射状に延在し、且つ、外側表面及び内側表面を備える環状フランジと、
を備えるボスと、
上記外側シェル内に配置された内側ライナであって、
上記フランジの上記外側表面に隣接する外側部と、
上記フランジの上記内側表面に隣接する内側部と、
上記内側部内の通気孔と、
を備える内側ライナと、
を備える圧力容器。
上記ライナは、上記内側環状溝内に受容された内側環状タブを備え、
上記通気孔は、上記内側部において、上記内側環状タブよりも半径方向外側に配置されている、
項目1に記載の圧力容器。
項目5.上記通気孔は円形である、項目1〜4の何れかに記載の圧力容器。
項目7.圧力容器を形成するための方法であって、
ボスをマンドレルに取り付けることであって、
上記ボスは、
内室と上記圧力容器の外部との間の流体連通のために構成されたポートと、
上記ポートから放射状に延在し、且つ、外側表面及び内側表面を備える環状フランジと、
を備える、ボスをマンドレルに取り付けることと、
上記フランジの周囲に非金属ポリマーを流して、上記圧力容器の内側ライナを形成することであって、
上記内側ライナは、
上記フランジの上記外側表面に隣接する外側部と、
上記フランジの上記内側表面に隣接する内側部と、
を備える、上記フランジの周囲に非金属ポリマーを流して、上記圧力容器の内側ライナを形成することと、
上記ライナの上記内側部内に通気孔を形成することと、
上記ライナ、及び、上記ボスの上記フランジの少なくとも一部、を包囲する外側シェルを形成することと、
を備える方法。
上記内側ライナを形成することは、上記内側環状溝に上記ポリマーを流して、上記内側環状溝内に受容される内側環状タブを形成すること、を備える項目7に記載の方法。
項目10.上記通気孔を形成することは、上記環状フランジと上記ライナとの間のインタフェースを上記内室と流体接続するために、上記ライナの上記内側部を通る開口を設けること、を備える項目7〜9の何れかに記載の方法。
本概要は、詳細な説明において以下でさらに説明される概念を、単純化された形態で紹介するために提供される。本概要は、開示されるか、または、請求項に挙げられる主題の、重要な特徴、または、本質的な特徴を特定することを意図しておらず、さらに、開示されるか、または、請求項に挙げられる主題の、開示されたそれぞれの実施形態、または、全ての実施を説明することを意図していない。具体的には、1つの実施形態に関してここで開示された特徴は、他にも同様に適用され得る。さらに、本概要は、請求項に挙げられる主題の範囲を特定するための補助として用いられることを意図していない。多くの他の新たな有利な点、特徴、及び、関連性は、この説明が進むにつれて明らかになるであろう。以下に続く図及び説明は、具体的な実施形態をより詳細に例示する。
[詳細な説明]
高圧下におけるライナとボスとの分離を防止し、制御不能な漏れを防止し、さらに、ライナとボスとの間に閉じ込められたガスの放出を可能にする、ライナとボスとのインタフェース構造の必要性が残る。本開示は、圧力容器10’のライナ20’とボス16との間でガスが増大することを防止する特徴を備える圧力容器に関する。例えば、図3に示されるように、通気孔52は、通路を提供し、ガスが、この通路を通って、ボス16とライナ20’との間のインタフェースから容器10’の内室55に放出されうる。内室55は、ライナ20’内の内部空間として規定される。たとえ、ボス16とライナ20’とのインタフェース間にガスがあったとしても、ガスは通気孔52を通って逃げることができるので、このようなガスは増大せず、容器10’は、ボス16のフランジ22とライナ20’との間の確実な封止を発揮する。
