Abstract: A rotating machine for delivering a working fluid to a system includes a compressor housing defining a compressor housing interior and partially defining a flow path. The rotating machine also includes a shaft and a compressor wheel disposed in the compressor housing interior. The rotating machine additionally includes a backplate coupled to the compressor housing and further defining the flow path. The backplate and the compressor housing are configured to direct working fluid from the compressor housing interior through the flow path. The backplate defines a working fluid connection adjacent the compressor wheel and/or the flow path such that the working fluid connection is fluidly coupled to the flow path and such that the compressor wheel delivers working fluid from the compressor housing interior and the working fluid connection to the flow path.
