Claims (8)
- 流体を収容した容器(1)に組み付けられる定量バルブであって、
計量室(20)を収容するバルブ本体(10)と、
前記計量室(20)から流体を選択的に吐出するために、前記バルブ本体(10)内を軸方向に、静止位置と吐出位置との間で摺動するバルブ部材(30)とを備え、
前記バルブ部材(30)は、カラー部(320)を有し、第1に前記バルブ本体(10)と、第2に前記カラー部(320)と協働するバネ(8)によって前記静止位置へと付勢され、
前記バルブ本体(10)は、バルブ本体筒状部分(15)を有し、前記バルブ本体筒状部分(15)内で、前記バルブ部材(30)の前記カラー部(320)が静止位置と吐出位置との間を摺動し、
前記バルブ部材(30)は、
吐出位置から静止位置へと戻るたびに、前記容器(1)を前記計量室(20)に連通させて、当該定量バルブが前記容器(1)の下方に配された倒立姿勢にあるうちに、前記流体を前記容器(1)から内部経路(33)を経由して前記計量室(20)に充填し、
静止位置においては、計量室ガスケット(22)と協働することによって、前記計量室(20)が前記容器(1)から実質的に隔離され、前記計量室(20)から前記内部経路(33)を経由してのみ前記容器(1)に連通した状態を保ち、
前記カラー部(320)は、静止位置において、前記内部経路(33)から前記容器(1)に至る連通経路上に配され、
前記バルブ本体筒状部分(15)は、前記バルブ本体筒状部分(15)の長さの少なくとも一部にわたって延伸する複数の長手方向リブ(100)を有し、
前記長手方向リブ(100)は、径方向内側に突出し、前記バルブ部材(30)の前記カラー部(320)に作用して、前記カラー部(320)を前記バルブ本体筒状部分(15)内の実質的に中央に配して、前記カラー部(320)が静止位置にあるときの、前記カラー部(320)の外側と前記バルブ本体筒状部分(15)の内面との間の機能的な間隙を通じた、前記計量室(20)に充填された流体の喪失を解消または緩和する
ことを特徴とする定量バルブ。 - 前記バルブ本体筒状部分(15)が有する前記長手方向リブ(100)は、少なくとも3つ、望ましくは6つである
請求項1に記載の定量バルブ。 - 前記各長手方向リブ(100)は、丸みを帯びた形状を有し、前記カラー部(320)との接触面積が最小限であり、
前記バルブ本体筒状部分(15)は前記軸方向に長尺な長尺開口(11)を1つ以上有し、
前記長手方向リブ(100)は、前記軸方向に対する周方向において、前記長尺開口(11)とは異なる位置であって、かつ、
前記軸方向において、前記カラー部(320)の前記静止位置から前記吐出位置に向かって、前記長尺開口(11)の少なくとも一部と重複する範囲まで延設されており、当該長手方向リブ(100)の延設方向端部の、前記周方向における幅が、前記延設方向に向かうに伴って狭くなっている
請求項1又は請求項2に記載の定量バルブ。 - 前記バルブ部材(30)は、前記定量バルブの作動終了の度に前記計量室(20)を充填する内部経路(33)を有し、
前記バルブ本体筒状部分(15)は、前記カラー部(320)と前記計量室(20)との間で規定される第2室(29)を収容し、
前記第2室(29)は、前記静止位置においては、前記内部経路(33)を経由して前記計量室(20)に連通している
請求項1から請求項3までの何れかに記載の定量バルブ。 - 前記バルブ本体筒状部分(15)の内径と前記カラー部(320)の外径との差は、0.2mmより小さく、望ましくは0.15mmより小さく、前記定量バルブの前記静止位置において、前記第2室(29)に収容された流体が前記第2室(29)内に概ね保持され、
前記長手方向リブ(100)は、0.1mmより小さい、望ましくは0.09mmより小さい、さらに望ましくは約0.07mmの径方向寸法d2を有し、前記カラー部(320)と前記長手方向リブ(100)との間の径方向周縁間隔が、0.06mmより小さく、望ましくは0.02mmより小さい
請求項4に記載の定量バルブ。 - 前記径の差は、0.01mmより大きく、具体的には小さくとも0.04mmである
請求項5に記載の定量バルブ。 - 前記長手方向リブ(100)の径方向寸法d2は、前記カラー部(320)の前記静止位置において最大となり、前記カラー部(320)の前記吐出位置において最小となるように減少する
請求項1から請求項6までの何れかに記載の定量バルブ。 - 流体吐出装置であって、請求項1から請求項7までの何れかに記載の定量バルブが、容器(1)に固定されている
