PROBLEM TO BE SOLVED: To provide a compressor of an exhaust turbosupercharger in which a part of the air flowing through an impeller is taken in from an inlet slit opening to an air passage at the peripheral portion of the impeller and discharged from an outlet slit to a compressor inlet air passage through a recirculation passage and noise is reduced and performance is increased by a simple strucure without replacing a compressor housing even in an existing compressor. SOLUTION: This compressor 200 is so formed that the part of the air is taken in from the inlet slit 7 opening to the air passage at the outer periphery of the impeller 2 and discharged from the outlet slit opening to the compressor inlet air passage to the compressor inlet air passage 100 through the recirculation passage. The outlet slit 9 is formed aslant by a specified angle to an acute angle relative to the radial direction of the impeller so that an air flowout centerline to the compressor inlet air passage is directed toward the impeller 2. The passage area of the outlet slit is larger than the passage area of the inlet slit 7. COPYRIGHT: (C)2007,JPO&INPIT |
