- 軸方向流入口(14)および第1の軸方向流出口(16)を有し、前記第1の軸方向流出口(16)が全周にわたって円周状に延びているリング状流路(12)と、
前記第1の軸方向流出口(16)に隣接し、かつ、同軸状に設けられ、軸方向に流入する粒子の流れを半径方向の流れに変換すると同時に、加速するための複数の案内羽根(26)が全周に渡って分布するように設けられている方向変換チャンバ(18)と、
前記方向変換チャンバ(18)の外径と同じ寸法で、かつ、同軸状に設けられ、周囲壁がほぼ円筒状からなり、軸方向流出側に設けられている第2の軸方向流出口(24)の内径が前記方向変換チャンバ(18)の内径より小さい回転チャンバ(20)と、
前記回転チャンバ(20)の前記第2の軸方向流出口(24)に隣接し、かつ、同軸状に設けられ、周囲壁(32)が流出口に向かって凹面状に拡大されている領域を有する放出流路(30)と、
からマウスピース(10)が構成されており、
前記方向変換チャンバ(18)により、重い粒子を衝突させ、前記周囲壁(32)に沿って循環させ、前記循環によって、吸入方向に対して横方向の比較的高い速度成分を有する前記回転チャンバ(20)の前記第2の軸方向流出口(24)からの流出粒子が、前記放出流路(30)の領域内で減速されることを特徴とする粉末吸入器用分散装置。 - 前記案内羽根(26)は、湾曲しており、その曲率が軸方向に向かって低減することを特徴とする請求項1に記載された粉末吸入器用分散装置。
- 前記案内羽根(26)は、その断面において、湾曲した輪郭線を備えて流線形の翼形状を有することを特徴とする請求項1または請求項2に記載された粉末吸入器用分散装置。
- 前記案内羽根(26)は、前記方向変換チャンバ(18)の流入部の領域において丸められた前端部を有し、前記方向変換チャンバ(18)の流出部の領域において、より小さい丸みの後端部を有することを特徴とする請求項1から請求項3のいずれか1項に記載された粉末吸入器用分散装置。
- 前記放出流路(30)は、鋭いエッジをもって、前記回転チャンバ(20)に隣接していることを特徴とする請求項1から請求項4のいずれか1項に記載された粉末吸入器用分散装置。
- 前記リング状流路(12)、第1の軸方向流出口(16)、前記回転チャンバ(20)の第2の軸方向流出口(24)は、外部空気供給用の開口がないように一体に構成されていることを特徴とする請求項1から請求項5のいずれか1項に記載された粉末吸入器用分散装置。
