PROBLEM TO BE SOLVED: To facilitate the maintenance as well as preventing the breakage of a lubrication oil head tank.SOLUTION: A mounting support 27 disposed between a lubrication oil head tank 24 storing lube oil and a compressor impeller 14 and an air labyrinth 28 are arranged to separate the compressor impeller 14 and the lubrication oil head tank 24; and a mounting support flange 34 of the mounting support 27 is arranged on the compressor impeller 14 side of an air labyrinth flange 36 of the air labyrinth 28. Such an exhaust turbine supercharger can easily attach/detach the mounting support 27 with respect to a bearing stand body casing 21 while installing the air labyrinth 28 to the bearing stand body casing 21, so that the maintainability is improved; and besides when the compressor impeller 14 is broken, broken pieces of the compressor impeller 14 are prevented from directly impinging upon the bearing stand body casing 21, so that the breakage of the lubrication oil head tank 24 can be prevented.SELECTED DRAWING: Figure 2 |
