Description
即ち、スリーブが軸方向に長い構成の場合、その開口端が拡開するよりも、同スリーブの中間部分が膨らんでしまう可能性がある。しかしながら、上記構成により、開口端とは反対側の軸方向端部に近い部分、或いは不要な膨張が生ずる可能性のある中間部分に高剛性部を設定することで、スリーブは、その開口端近傍が、優先的に拡開するようになる。その結果、より高精度に安全弁として機能させることができるようになる。
以下、本発明を具体化した第1の実施形態を図面に従って説明する。
図1に示すように、本実施形態の安全弁1は、高圧ガス流路2に連通するとともに軸方向の一端(同図中、上側の端部)が「底部(又は蓋部)」を有しない開口端3として形成された略円筒状の筒体4と、その開口端3を気密に封止する閉塞体5とを備えている。
(1)安全弁1は、開口端3を有して高圧ガス流路2に連通する筒体4と、開口端3を気密に封止する閉塞体5とを備える。そして、ガス圧に応じた筒体4の変形に基づき開口端3が拡開してガスを漏出させることにより、許容水準を超えたガス圧の上昇を抑制する。
即ち、ガス圧の上昇に伴う開口端3の拡開により当該開口端3の内周面14と閉塞体5側の挿入部11との間に隙間Xが形成された状況においても、両者の間に圧縮状態で介在されたOリング13が復元し、そのシール部材としての機能を喪失するまでは、開口端34を気密に封止された状態で維持することができる。従って、上記構成によれば、簡素な構成にて、容易且つ高精度に、そのガスが漏出するに至る圧力を制御することができる。加えて、その後、ガス圧が低下した場合には、その開口端3が縮径してOリング13を圧縮することにより、再度、当該開口端3を気密に封止する構成とすることも可能になる。
以下、本発明を、高圧水素ガスの供給系に設けられた電磁弁に具体化した第2の実施形態を図面に従って説明する。
次に、本実施形態の電磁弁に設けられた過剰圧抑制構造、即ち許容水準を超えたガス圧の上昇を抑制する安全弁としての機能について説明する。
(3)上記構成によれば、燃料電池車用のガスタンク等、高圧水素ガスの供給系に設けられた既存の電磁弁20を安全弁として機能させることができる。その結果、新たな構成を追加することなく、構成簡素且つ低コストにて、許容水準を超えたガス圧の上昇を抑制して、その安全性の向上を図ることができる。
・上記第2の実施形態では、本発明を、高圧水素ガスの供給系に設けられた電磁弁20に具体化した。しかし、これに限らず、その他の高圧ガス用の電磁弁に適用してもよい。
(イ)前記閉塞体と前記開口端との間に圧縮状態で介在されることにより該開口端を気密に封止可能なシール部材を備えること、を特徴とする電磁弁。これにより、請求項2と同様の効果を得ることができる。
Claims (2)
- 高圧ガス流路の途中に設けられた筒状のスリーブと、前記スリーブの径方向外側に設けられた電磁コイルの起磁力に基づき前記スリーブ内を移動するプランジャと、前記プランジャの移動に基づき前記高圧ガス流路を開閉可能な弁体とを備えるとともに、前記スリーブの軸方向端部は、閉塞体により気密に封止される開口端として形成された電磁弁であって、
ガス圧に応じた前記スリーブの変形に基づき前記開口端が拡開してガスを漏出させることにより、許容水準を超えた前記ガス圧の上昇を抑制する安全弁として機能すること、
を特徴とする電磁弁。 - 前記スリーブには、前記ガス圧に応じた変形量が前記開口端よりも小さい高剛性部が形成されること、を特徴とする請求項1に記載の電磁弁。
