ABSTRACT:
A buffer zone adjacent to the inner diameter of carbon seals of an enclosed bearing compartment is defined by an elongated element disposed adjacent the shaft of a turbine type power plant is open ended to receive pressurized, cool air bled from the compressor to apply the cooler, higher pressure air (higher than ambient) adjacent to the seal. One embodiment contemplates feeding the buffer zone by pipes and another embodiment shrouds the bearing compartment and flows the shrouded air to the buffer zone. The buffer air with other secondary airflow cooling requirements, is utilized to cool the high pressure turbine with an overall engine performance benefit.
