Patent abstract

An air cycle machine includes a housing having a compressor housing portion. A shaft is supported by the housing and includes a thrust runner. A hydrodynamic thrust bearing is arranged adjacent to the thrust runner and includes upstream and downstream sides. A compressor rotor is mounted on the shaft. A seal is arranged between the compressor rotor and the compressor housing portion. An orifice is provided in the compressor housing portion at the downstream side of the hydrodynamic bearing. The orifice vents hot compressed air that may leak past the seal prior to reaching the hydrodynamic thrust bearing.
