FIELD: machine building.
SUBSTANCE: invention relates to turbine compressors. The device novelty is that a gas receiving casing contains profiled front and radial channels for gases supply, connected with bottom left and right discharge channels of the gas receiving casing, respectively; its top channels are bypass for gas exhaust, at that the gas supply channels are connected by pairs with the bypass channels via the device controlling the turbine capacity in the form of two parallel rotating gates, installed on rollers at the input of the gas receiving casing controlled directly by pneumatic engines, and wherein the impeller is a combination of special profile blades made on a cylindrical and toroidal part with transitions from one geometric surface to another. In this device the technical result is ensured that is expressed in an increased efficiency and torque on the engine shaft. Besides, effective control of the turbine is ensured.
EFFECT: improved design.
