COMPRESSOR FOR EXHAUST TURBO-CHARGER

摘要

Disclosed is a compressor for an exhaust turbo-charger wherein an entrance slit, an exit slit, and a recirculation path can simultaneously be formed when combining a separate-type compressor housing, thereby attaining reduction in man-hours for assembly and costs of manufacturing, the structures around the entrance slit, the exit slit, and the recirculation path are miniaturized, and the structures and the shapes of the entrance slit, the exit slit, and the recirculation path are easy to adjust to improve the performance of the compressor. The compressor is characterized in that the matching surfaces of compressor housing members (9a, 9b) divided in the direction of the rotation axis (7) of an impeller (5) are formed in the compressor housing (9), in the vicinity of the entrance section of the impeller (5), and the space serving as the recirculation path (29), the entrance slit (25), and the exit slit (27) are formed between the compressor housing members (9a, 9b) to be combined.
