Abstract
A compressor assembly comprises a compressor having a rotor comprising a shaft with fan blades for compressing air. An air bearing serves to cool the shaft of the rotor. A compressor air inlet receives air for the fan blades, which is then exhausted from the fan blades out a compressor air outlet. An air flow path communicates air from the compressor air inlet to the air bearing. A valve controls the flow of air through the air flow path and has an open position permitting air through the air flow path and a closed position restricting air to the path.
