摘要：An air cycle machine (10) includes a housing having a compressor housingportion (70). A shaft (58) is supported by the housing and includes a thrust runner (66). Ahydrodynamic thrust bearing (68) is arranged adjacent to the thrust runner (66) and
includes upstream and downstream sides. A compressor rotor (65) is mounted on theshaft (58). A seal (74) is arranged between the compressor rotor and the compressorhousing portion. An orifice (84) is provided in the compressor housing portion (70) at thedownstream side of the hydrodynamic bearing (68). The orifice (84) vents hotcompressed air that may leak past the seal (74) prior to reaching the hydrodynamicthrust bearing (68).
