Abstract

A single-stage compressor device includes a housing and a rotating group with a shaft and a compressor wheel. The compressor wheel includes a front face and a back face. The front face cooperates with the housing to define a compressor flow path. A motor drives rotation of the rotating group within the housing. Furthermore, the compressor device includes a bleed system fluidly connected to the compressor flow path and configured to receive bleed fluid from the compressor flow path. The bleed system includes a bleed passage. At least a portion of the bleed passage is cooperatively defined by the back face of the compressor wheel and an opposing surface of the housing. The bleed system is configured to pass bleed air from the bleed passage, thereby alleviating thrust loading of the compressor wheel on the rotating group.
