Abstract

Ujawniono uklad, zawierajacy sekcje wydechowa turbiny, która zawiera wydechowy kanal przeplywowy. Wydechowa sekcja turbiny zawiera równiez zewnetrzna konstrukcje (42), majaca oslone (108), zewnetrzna scianke wydechowa (106) umieszczona wzdluz wydechowego kanalu przeplywowego, oraz zewnetrzna wneke (110) umieszczona miedzy zewnetrzna scianka wydechowa (106), a zewnetrzna oslona (108). Wydechowa sekcja turbiny zawiera ponadto wewnetrzna konstrukcje (38), majaca wewnetrzna scianke wydechowa (80) usytuowana wzdluz wydechowego kanalu przeplywowego, wewnetrzna wneke (91) usytuowana miedzy wewnetrzna scianka wydechowa (80) i wewnetrzna oslona (92) oraz wneke (82) lozyska usytuowana miedzy wewnetrzna oslona (92), a obudowa (85) lozyska. Dodatkowo, wydechowa sekcja turbiny zawiera rozpórke (40) rozposcierajaca sie miedzy zewnetrzna konstrukcja (42) i wewnetrzna konstrukcja (38). Rozpórka (40) zawiera pierwszy kanal przeplywowy (52), skonfigurowany do prowadzenia plynu z wewnetrznej wneki (91) do zewnetrznej wneki (110).
