ケーシング6の下端部は、回転軸7の軸線方向においてケーシング6を一点で支持する(回転軸7の軸線方向と直交する方向においては、二点以上で支持する場合もある)脚部6aとなっており、この脚部6aは、床面に設置された基台(図示せず)に固定されるようになっている。すなわち、排気タービン過給機1の重量は、この脚部6aを介して基台に伝達されるようになっている。
図中の符号Pはパンチング・プレートである。このパンチング・プレートPは、その一端部がタービン部3の下端部に固定されているとともに、その他端部がケーシング6の脚部6aと同様、基台に固定されている。そして、このパンチング・プレートPは、脚部6aのように排気タービン過給機1の重量を支持することを主たる目的とするものではなく、排気タービン過給機1が基台に対して動揺(振動)しないようにすることを主たる目的とするものである。
タービン11は、タービン・ロータ12と、タービン・ノズル13とを備えている。タービン・ロータ12は、回転軸7の一端部に設けられた、円盤状のタービン・ディスク12aと、このタービン・ディスク12aの外周上に取り付けられた、翼型断面を有する複数枚のタービン・ブレード12bとを備えている。
タービン・ノズル13は、複数枚のノズル・ガイド・ベーン13aを環状に配置して構成されたものであり、タービン・ブレード12bの上流側に配置されている。
コンプレッサ羽根車14は、回転軸7の他端部に取り付けられた、略円盤状のハブ14aと、このハブ14aの外表面から半径方向外側に向かって延びるとともに、周方向に沿って環状に設けられた複数枚の羽根14bとを備えている。
コンプレッサ部5の上流側には、前記内燃機関の吸気系統に接続された消音器(サイレンサ)16が隣接配置されており、この消音器16を通過した外気4は、流入路17を介してコンプレッサ羽根車14の羽根14bに導かれるようになっている。コンプレッサ部5の下流側には、図示しないインタークーラやサージタンク等が設けられており、渦巻き室15を通過した外気4は、これらインタークーラやサージタンク等を通過した後、前記内燃機関に供給されるようになっている。
図5に示すように、発電機ハウジング35およびカバー部材37には、断面視円形状を呈する(第1の)穴44が軸方向(図5において左右方向)に沿って所定の位置まで形成されており、発電機ハウジング35には、穴44と通路43の入口(図7Aおよび図7B参照)43aとを連通する(第1の)穴45が半径方向(図5において上下方向)に沿って形成されている。穴44の入口には、冷却媒体を穴44内に供給するための冷却媒体供給管46が接続されている。
一方、図6に示すように、発電機ハウジング35およびカバー部材37には、断面視円形状を呈する(第2の)穴47が軸方向(図6において左右方向)に沿って所定の位置まで形成されており、発電機ハウジング35には、穴47と通路43の出口(図7Aおよび図7B参照)43bとを連通する(第2の)穴48が半径方向(図6において上下方向)に沿って形成されている。穴47の出口には、穴47から冷却媒体を排出するための冷却媒体排出管30が接続されている。
通路43と穴48との繋ぎ目(接続部)にも、リング状部材49および凹所53,54がそれぞれ設けられている。
ライナ42と発電機ハウジング35とは、冷却媒体を通路43に供給する穴44,45および冷却媒体を通路43から排出する穴47,48と、通路43との各繋ぎ目に配置されたリング状部材49のみで接続(連結)されていることになる。
これにより、保守点検時に、ライナ42および固定子31を発電機ハウジング35から容易に取り外して、ライナ42および固定子31だけを交換することができ、保守点検費用を削減することができる。
発電機ハウジング35からのライナ42および固定子31の取り外し、および発電機ハウジング35へのライナ42および固定子31の取り付けが容易になり、分解・組立に要する時間を短縮することができ、メンテナンス性を向上させることができる。
これにより、発電機ハウジング35とライナ42との合わせ面、すなわち、発電機ハウジング35の内周面35aとライナ42の外周面42aとの間からの冷却媒体の漏出(流出)を確実に防止することができる。
これにより、ライナ42およびこのライナ42に取り付けられた(固定された)固定子31が周方向に回転することを防止することができる。
例えば、上述した実施形態では、通路43と穴45との各繋ぎ目および通路43と穴48との各繋ぎ目に、平面視環形状を呈するリング状部材49が配置されている。しかし、通路43と穴45との各繋ぎ目および通路43と穴48との各繋ぎ目に配置される部材の平面視形状は、環形状以外の形状(楕円形状、長方形状、正方形状、三角形状等のいかなる形状)であってもよい。
