Description
Claims (10)
- ターボ機械のロータホイール(100)のケーシング(10)であって、該ケーシングの軸を中心とする実質的に円筒形の内壁(15)を有しており、円筒形の壁が、複数の周状の溝(11、12、13)を有しており、各々の溝の断面が、軸断面において実質的に一定であり、周状の溝(11、12、13)の断面積(S1、S2、S3)が、上流から下流へと、最初の溝(11)から最後の溝(13)へと進むにつれて減少していることを特徴とする、ケーシング。
- 上流から下流への溝の断面積(S1、S2、S3)の減少が、線形である、請求項1に記載のケーシング。
- 前記周状の溝のうちの最初の溝の深さ(E1)が、より下流に位置する後続の溝(12、13)の深さ(E2、E3)よりも大きい、請求項1または2に記載のケーシング。
- 前記周状の溝の深さ(E1、E2、E3)が、上流から下流へと減少している、請求項1から3のいずれか一項に記載のケーシング。
- 前記周状の溝の深さの減少が、線形である、請求項4に記載のケーシング。
- 前記周状の溝のうちの最初の溝(11)の幅(D1)が、より下流に位置する後続の溝の幅(D2、D3)よりも大きい、請求項1から5のいずれか一項に記載のケーシング。
- 前記周状の溝の幅(D1、D2、D3)が、上流から下流へと減少している、請求項1から6のいずれか一項に記載のケーシング。
- 隣り同士の溝の間の実質的に円筒形の接続面(16、17)を呈しており、接続面の直径が、溝の上流および下流でそれぞれ測定されるケーシング(10)の内径(B1、B2)の平均値に実質的に等しい、請求項1から7のいずれか一項に記載のケーシング。
- 溝(11、12、13)の各々が、実質的にケーシングの軸(F)に垂直な平面内を延びている、請求項1から8のいずれか一項に記載のケーシング。
- ロータホイール(100)と、請求項1から9のいずれか一項に記載のケーシングとを含む、ターボ機械。
