Abstract
Description
(シリンダの内径)/(密閉容器の内径)≧0.4
となる際に前記液面高さの確保が困難である。
(凹部19とシリンダ内壁11間距離)≧(孔15bとシリンダ内壁11間距離)となる条件を設定することで、凹部19からシリンダ内壁11間の洩れを防止することができる。また低圧チャンバ方式においては、前記空間51は低圧ガスで満たされることとなり前記孔15b間の洩れを防止するため、前記凹部19と前記孔15b間の距離は、
(凹部19と孔15b間距離)≧(孔15bとシリンダ内壁11間距離)
とすることが条件となる。ここで上記それぞれの条件設定の基準とした(孔15bとシリンダ内壁11間距離)の具体的な数値を実験的に求めた結果、少なくとも2.5mm以上とする必要がある。また、本実施例においては前記シリンダ10における凹部の設定法を述べたが、同様の設定法にて前記閉塞部材60である上軸受61,仕切り板62,下軸受63に設けることも可能である。
