Claims (1)
- 密閉容器に作動流体導入口と作動流体排出口と液体流入口及び液体排出口が設けられ、密閉容器内にフロートと切替え弁及びスナップ機構が内蔵され、スナップ機構は、密閉容器内に支持された揺動軸と、揺動軸の周りに回転するフロートアーム及び副アームと、フロートアームに支持された第1の軸と、副アームに支持された第2の軸と、第1及び第2の軸の間に取り付けられたバネを有し、フロートがフロートアームに連結され、切替え弁が動力伝達軸を介して副アームに連結され、密閉容器内に溜った液体の液面の高さに応じて切替え弁が作動流体導入口の給気弁口と作動流体排出口の排気弁口の開閉を切り換えて、初めに排気弁口を開き給気弁口を閉じて液体流入口から液体を流入させ、次いで排気弁口を閉じ給気弁口を開いて密閉容器内に溜った液体を液体排出口から圧送する液体圧送装置において、密閉容器内に支持された単一のストッパ軸を設け、当該ストッパ軸が貫通しフロートの浮上に伴うフロートアームの回転範囲が規制される窓をフロートアームに開け、前記ストッパ軸が貫通しフロートの降下による副アームの回転範囲が規制される窓を副アームに開けたことを特徴とする液体圧送装置。
