Description
・ アダプタをインパクタに対して取外し可能に固定する固定手段、
・ アダプタがカップに対して固定され次第、アダプタとカップとの間に自由空間を残す、カップ上の固定手段、
・ アダプタとカップとの間の自由空間が外側と連絡するところのアクセスホール、
を有し、
・ カップは、その凹状遠位面上に、摺動表面を周辺リップに向かって延在させる円筒形又は僅かに円錐形の環状保持表面を有し、
・ アダプタは、カップの環状保持表面と同一の形状である、円筒形又は僅かに円錐形の環状係合表面を有し、
・ その結果、アダプタは、カップの環状保持表面において半径方向にグリップされる環状係合表面を有して、流体密封に強制的に保持され得る。
a) アダプタをその寸法を低減するよう冷却する段階、
b) カップにおいてアダプタを位置付ける段階、
c) アダプタの環状係合表面がカップの環状保持表面において流体気密であるよう強制的に不動にされるよう、アダプタがカップにおいて配置され次第膨張するよう室温に戻ることを可能にする段階、
である。
a) アダプタ2は、その寸法を僅かに低減するよう十分に低い温度まで冷却される。該寸法は、最初はアダプタ2の環状係合表面7aの直径が同一温度においてカップ1の環状保持表面5bの直径より僅かに大きいようにされる。アダプタ2の温度を低下することは、それ自体は室温のままにとどまるカップ1の入口との係合を促進するよう、アダプタの外径を低減させる。
b) 続いてアダプタ2は、周辺リブ12が周辺リップ6で終端となるよう、カップ1において位置付けられる。
c) カップにおいて配置され次第、アダプタ2は、それを拡大するよう室温まで戻ることを可能にされる。そのため、アダプタ2は、環状係合表面7aによってカップ1において流体気密であるよう強制的に適合及び強制的に保持される。
