Abstract: A system for controlling a flow rate of a compressed cooling medium between a compressor section and a turbine section of a gas turbine includes a flow path that is defined between the compressor section and the turbine section of the gas turbine and a thermally actuated variable flow valve disposed within the flow path. The variable flow valve defines an opening that changes in size based on a temperature of the compressed cooling medium flowing therethrough.
