In a turbine engine (10), low temperature air is diverted from a low pressure section of the compressor section of the engine to cool the high pressure turbine of the engine. Low pressure air is diverted from the compressor section, and its pressure is thereafter be increased. the pressure is increased in an intermediate cavity (80) in the engine, where rotational energy of the diverted air is converted to static pressure by way of an obstruction (88) that converts dynamic head of the air in the cavity into static pressure.
