Abstract: An air cooled gas turbine engine includes a cooling flow valve for regulating cooling air flow to a turbine rotor in accordance with compressor discharge pressure and the operating temperature of the turbine component by means of a pressurizable diaphragm carrying a movable valve element with respect to a fixed valve seat and wherein means are associated with the diaphragm to define a pressurizable internal cavity communicated with compressor discharge pressure by means of a control orifice to bias the diaphragm and valve element into a closed position when the compressor discharge pressure is at engine cruise condition and wherein as the temperature of operating turbine blades increase means are provided to sense such temperature increase and to bleed air from the pressurizable chamber thereby to cause the movable valve element to cycle with respect to the fixed valve seat so as to modulate coolant flow to the turbine in a manner to maintain optimized engine power output along with improved fuel consumption characteristics.
