Abstract
A compressor housing (12) for a turbocharger includes a recirculation cavity (4) formed in a portion of the compressor housing (12). The recirculation cavity (4) is defined by an inner cavity wall (2) and an outer cavity wall (5). In addition, an inlet groove (1) and an outlet (7) are formed in the recirculation cavity (4) for circulating airflow from the compressor housing (12) through the recirculation cavity (4), and at least one recirculation noise obstruction (6) is fixedly secured within the recirculation cavity (4) to disrupt air flow through the cavity and reduce noise in the compressor housing (12).
