Compressor cover for turbochargers
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 (...

| description | 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. |
