Compressor gas flow deflector and compressor incorporating the same

A compressor for a turbocharger, comprising:

• a compressor housing, the compressor housing having a housing wall, the housing wall comprising a shroud having an inner wall that defines a central air channel of the compressor, the shroud defining a compressor inlet in fluid communication with the central channel;
• an inlet duct that is sealingly disposed over the compressor inlet, the inlet duct comprising a duct air channel that is configured to provide air to the compressor inlet and main air channel;
• a compressor wheel rotatably disposed within the shroud proximate the inner wall and attached to a driven shaft, the wheel comprising a plurality of circumferentially-spaced, axially-extending compressor blades that radially protrude from a hub, the blades 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 upon rotation of the wheel;
• 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;
• and
• a deflector comprising 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.
