Abstract
The cooling air flowpath for a turbomachine includes a plurality of valves placed in mutually parallel relationship to collectively provide for the modulation of the cooling airflow. Minimum flow requirements are assured while economizing on air to increase efficiency. Any single valve passes only a small portion of the total air so that a valve failure does not appreciably reduce the overall cooling function.
