Description
上述の圧力制御デバイスの機能は、以下の通りであり、要求されたように過圧で、しかし、好ましくは、約8バールの過剰で、不活性ガス、特に、通常の空気が、第2チャンバ7内に充填されている。弁24は、その閉位置にある(図1)。1.5乃至2.0バール、好ましくは、2.0バールの一定の所定の過剰圧力で、ガス、特に、通常の空気が第1チャンバ16内に充填されている。容器50内の液体が弁51によって小出しされるならば起こることであるが、容器50内の圧力が所定の過剰圧力以下に下がると、通路内の圧力も低下する。かくして、第1チャンバ16と通路との間に圧力平衡は最早なく、ピストン13は、弁25の閉位置(図1)から開位置(図2)まで、下方に移動する。シリンダ2の第2チャンバ7内には過圧があるため、容器50、すなわち、可撓性ピストン52の下まで通路に亘って空気流があり、可撓性ピストン52は、第1チャンバ16と通路(又は、容器50)との間に再び圧力平衡になるまで上方に移動される。平衡状態では、弁25は再び閉じられ、可撓性ピストン52の下側圧力と上側圧力とは同じになる。ピストン13は、平衡状態に達するまで、往復する仕方で又は振動する仕方で移動されて、弁25を開閉する。ピストン13及びステム17は軽量であるため、弁25の開位置と閉位置との間の往復運動は大変速く、平衡状態に、ほとんど即座に到達する。
P2≧P1*(1+V1/V2)
ここで、P1=所定の過剰圧力
P2=第2チャンバ内の初期圧力
V1=容器の容積
V2=第2チャンバの容積
圧力制御デバイス1のシリンダ2は、好ましくは、ポリエチレンテレフタレート(PET)で射出吹込成形される。シリンダ2を生産するための射出吹込成形工程の主な利点は、異なる寸法を同じ成形型で、若しくは、最小限の変更で生産することができ、且つ、吹き込み工程中、延伸されたPET材料の配向が、高い強度及び良好なガス遮断特性を与えるより高い結晶構造をもたらすことである。典型的には、1.5乃至2.0mmの肉厚を有する、首部分3、フランジ4及び拡げられた又はより広い端部分32を有するシリンダ2の構造が大変強く、高圧ガスを収容するのに最も適していることが、証明された。
