Abstract
A compressor includes a compressor housing defining a cavity, and a compressor wheel disposed in the cavity, the compressor housing defining an inlet for leading air into the compressor wheel, a discharge volute for receiving air compressed by the compressor wheel, and a recirculation duct connected to the inlet at a location upstream of the compressor wheel. A recirculation valve is disposed between the discharge volute and the recirculation duct for regulating air flow through the recirculation duct into the inlet. The recirculation duct defines multiple parallel channels, the multiple parallel channels respectively conducting multiple parallel streams of air from the recirculation valve into the inlet.
