Description
前記ハウジングの下方空間に上下摺動可能に配置され、前記ハウジングの連通孔を通して流入する液体によって浮上するように構成されたフロートと、
前記フロートの上部に揺動自在に支持され、前記フロートが所定高さまで浮上したとき、前記弁座に当接して前記開口部を閉塞する可動弁と、
前記可動弁の外周を囲む枠状をなし、前記可動弁を前記フロートに対して所定の距離で昇降可能かつ傾動可能に保持するように、前記フロートの上部外周に装着された保持枠とを備え、
前記可動弁の前記フロートに対する昇降高さを規制する前記保持枠と前記可動弁との当接部に周方向に偏った凸部が形成されており、閉弁状態で前記フロートが下降するとき、前記凸部が当接して前記可動弁に下降力を付与するように構成されており、
前記可動弁の前記フロートに対する昇降高さを規制する前記保持枠と前記可動弁との当接部に形成された凸部の高さは、前記フロートの下端外周が前記ハウジングの内面に当接して、前記可動弁に対して前記フロートが最大に傾動した状態でも、前記保持枠と前記可動弁とが前記凸部のみで当接するように設定されていることを特徴とするフロート弁装置を提供するものである。
