TURBO-UNIT Russian patent published in 2019 - IPC F03B3/00 F03B13/00 

FIELD: turbines or turbomachines.

SUBSTANCE: invention relates to turbine units. Turbo-unit 1 comprises working chamber with casing 12 and rotor 2 with central section 7 built into the chamber and front and rear sections arranged outside the chamber. Section 7 has transverse annular ribs 8. On ends of ribs 8 fixed blades 10 assembled into annular groups 11. Casing 12 has closing section 7 shell 13, walls 14, 15 with windows 16, 17 for front and rear sections of rotor 2, adjacent to wall 14 chamber 21 with inlet branch pipe 22, adjacent to wall 15 outlet branch pipe 23. Shell 13 is equipped with ribs 26 directed to rotor side and alternating with ribs 8. Longitudinal channels between ribs 8 are made in ribs 26 in the form of confuser nozzles and assembled into ring groups having a common cylindrical symmetry surface aligned with conditional cylindrical symmetry surface of blades 10, and individual conditional confuser symmetry planes unfolded relative to longitudinal sections planes of unit 1. Conditional cylindrical surfaces of symmetry of blades 10 and nozzles are offset from longitudinal axis of symmetry of unit 1 in radial direction. First rib 26 with nozzles is used as rear wall 29 of chamber 21.

EFFECT: invention is aimed at increasing power and reliability.
