FIELD: machine building.
SUBSTANCE: turbine guide vane has an aerodynamically curved working part of the blade, which has the channel system of the channel areas equipped with a throttle element for guiding the coolant. A throttle element is configured to select the coolant. In this case the throttle element is inserted into the turbine guide vane and is formed as a cup with the inlet for the coolant located on the circumferential side. The hole of the throttle element cup disposed in the outer surface of the turbine guide vanes.
EFFECT: creation of the turbine guide vanes, which, despite the outlet opening located in place of a reversal for the coolant outlet from the turbine blade, then the orificing is possible.
