CONSTITUTION: A damage preventing unit comprises a compressor impeller(1), an outer compressor casing(20), and a casing insertion unit(10). The casing insertion unit is disposed on the radius outer side of the compressor impeller. The casing insertion unit comprises a wall outer surface(11) of the insertion unit. The casing insertion unit contacts an axial stop unit(21) of the outer compressor casing. Provided is the flexible member(111) for transferring the axial force from the wall outer surface of the insertion unit to the outer compressor casing. The flexible member comprises two or more ribs(14,15) and a supporting member(13).</p> |
