Abstract: A refrigerant compressor according to an exemplary aspect of the present disclosure includes, among other things, an impeller arranged in a main flow path and including a plurality of vanes. The impeller is configured to rotate about an axis. A channel is outside the main flow path. A first orifice fluidly couples the channel to the main flow path upstream of the vanes, and a second orifice fluidly couples the channel to the main flow path downstream of leading edges of the vanes.
