Description
ハウジングと、
前記ハウジングの内周に軸方向変位可能に挿入されるシールリングであって、
先端面と、
パッキン装着空間を画定する後端面と、
を有するシールリングと、
前記ハウジングと前記シールリングの間をシールするパッキンであって、前記パッキン装着空間に配置されるパッキンと、
前記シールリングの後端面側に配置され、前記シールリングを先端面側に弾性付勢するバネ手段と、
を有する。
ハウジングの内周にシールリングを挿入し、
次に、前記シールリングの後端面によって画定されるパッキン装着空間に、パッキンを挿入し、前記ハウジングと前記シールリングの間をシールし、
次に、前記シールリングの先端面側に前記シールリングを弾性付勢するバネ手段を、前記シールリングの後端面側から挿入する。
図1を参照して、本実施形態の密封装置を説明する。本実施形態の密封装置11は、自動車関連の分野において油や冷却水等の流体を制御対象とする流量制御バルブに用いられるバルブ用シールである。バルブロータ21は、シールリング13が摺動可能に接触する相手部品である。バルブロータ21は円筒面状の外面21aを有する。また、外面21aには、複数のポート穴22が形成されている。なお、図1には1つのみのポート穴22が示されている。
なお、PTFE等の粉末材料を金型に押し固めて成形する場合、テーパー面13dを有するシールリング13は成形性に優れる。
なお、ストッパリング16の挿入は省略してもよい。
また、バネ手段15の挿入後に、ハウジング12の後端部側からストッパリングを挿入してもよい。
図4を参照して、本実施形態の密封装置を説明する。なお、本実施形態の密封装置の構造は、基本的に第1実施形態の密封装置と同様である。そのため、第1実施形態と同様の構成については同一の参照符号を用いることにより詳細な説明を省略し、第1実施形態と異なる構成について、以下に説明する。
なお、ストッパリング16の挿入は省略してもよい。
また、バネ手段15の挿入後に、ハウジング12の後端部側からストッパリングを挿入してもよい。
