Abstract
A turbocharger compressor includes a compressor housing having a housing wall that includes a shroud that defines a central air channel and a compressor inlet in fluid communication with the central channel and an inlet duct. It also includes a compressor wheel configured to draw air into the compressor inlet from the inlet duct and create a main airflow in the central air channel axially toward a compressor outlet. The compressor also includes a bypass channel that extends between an opening in the main channel located between the compressor inlet and compressor outlet proximate the compressor blades and the compressor inlet. The compressor also includes a deflector that includes a deflector surface that is configured to direct a bypass airflow in the bypass channel, and flowing in a direction from the main channel toward the compressor inlet, into the compressor inlet axially and radially inwardly toward the compressor wheel.
