FIELD: machine building.
SUBSTANCE: invention relates to turbine production, and more specifically to jet-reactive turbine (such as Segner wheel), and can be used as power drive element in drives of different purpose. According to invention, inlet nozzle is made with central body axially located in its housing, which outlet part is made with cone-shaped surface, converging in working medium flow direction, at outlet, housing inner surface is also made cone-shaped, converging along flow directly to edge cross-sectional area, wherein housing is located relative to shaft end input cross-section with axial clearance, complying with selected condition.
EFFECT: power losses are reduced and thereby turbine efficiency is increased, requirements to its structural-technological execution are reduced, as well as increased reliability of its operation with contaminated and/or wet working medium.
