FIELD: instrument engineering.
SUBSTANCE: steam turbine (10) has outer housing (22) and inner housing (12) located in external housing. Inner housing is horizontally divided in axial direction (16) into upper part (24) and lower part (26). Steam turbine also comprises active stage (40) located in inner housing (12), wherein inner housing is configured to supply fluid medium into active stage (40) along the entire circumference. Steam turbine also comprises at least one reactive step (42) having blades. Said at least one reactive stage is built into inner housing with provision of pressure limitation acting on external housing.
EFFECT: simplified assembly and increased efficiency of seals is achieved.
