Abstract: A compressor inlet recirculation system is disclosed. The compressor inlet recirculation system may have a compressor housing. The compressor inlet recirculation system may also have a compressor impeller disposed within the compressor housing. The compressor inlet recirculation system may further have an inlet flow guide attached to the compressor housing. The inlet flow guide may be configured to direct air to the compressor impeller. The inlet flow guide may have an inlet slot and an outlet slot spaced axially from the inlet slot. The compressor inlet recirculation system may also have an annular air passage extending between the inlet slot and the outlet slot.
