Abstract

The invention relates to a turbine guide vane (10) having an aerodynamically bent vane airfoil (14) which has a channel system (28) equipped with a throttle element (32) said channel system comprising channel sections (26) for the guidance of coolant. In order to provide an alternative turbine guide vane (10) by means of which both a partial coolant flow flowing in the interior and a partial coolant flow guided out of the turbine guide vane (10) are adjustable it is proposed that the throttle element (32) is designed for the removal of coolant.
