Abstract (en)

[origin: CN207406386U] The utility model relates to a geometry characteristics structure and turbine compressor reducer are drawn in returning of turbine compressor reducer draws how much characteristics structures for thistime and is used for the flowing of the first and second compressor reducer levels of turbine compressor reducer to connect, wherein, returning and drawing how much characteristics structures and have a plurality of arrange, part along partial spirals of circumference orientation trend at least along circumference orientation uniform distribution, the at least range selector ground of this part spiral forms the flow path who is used for the connection of flowing of the first and second compressor reducer levels who divides liftoff trend each other. The utility model has the beneficial effectsof, according to the utility model discloses a turbine compressor reducer can reduce mobile risk of cuting and minimizing loss of pressure.
