Abstract
A compressor device includes a housing and a shaft supported for rotation within the housing. The compressor device includes a compressor section with a compressor wheel. Also, the compressor device includes a thrust suppression section with a chamber and a thrust balance body disposed within the chamber. Moreover, the compressor device includes a motor configured to drivingly rotate the shaft, the compressor wheel, and the thrust balance body. The thrust balance body divides the chamber into a first sub-chamber and a second sub-chamber. Additionally, the compressor device includes a bleed air system that fluidly connects the compressor section and the thrust suppression section. The bleed air system is configured to bleed air from the compressor section, through the first sub-chamber, to the second sub-chamber, pressurizing the first sub-chamber and generating a counterbalancing thrust load that counterbalances a compressor thrust load on the shaft.
