摘要：<p>A compressor housing (16) for a turbocharger with a recirculation cavity (60) formed between a volute base portion (40) an inducer (44) and an inlet section (46) to bleed airflow from a compressor impeller (14) back into the inlet section (46). Bleed airflow can enter an angled recirculation slot (70) adjacent to the compressor impeller (14) and then flow through a recirculation cavity (60) formed in the compressor housing (16) to an inlet re entry slot (72) in the inlet section (46). Such recirculated airflow can improve surge margin. The inducer (44) includes a ring (50) with an inner surface (56) that preferably aligns with a converging wall (54) of the inlet section (46) which may be a separate piece attachable to a base of the compressor housing (16). Normal airflow from the compressor impeller (14) continues through the volute base portion (40) to an engine intake manifold.</p>
