<P>PROBLEM TO BE SOLVED: To provide a structure that distributes air and gas to be injected to a compressor equally in amount over a peripheral surface of an inflow passage, so that a gaseous medium and air are mixed and a turbulence generated by blow-in of a suction flow is removed. <P>SOLUTION: A cylinder-shaped muffler includes: an air exit aperture 54 connected to an inflow passage of a compressor of a turbocharger; and a passage that extends toward the air exit aperture and performs at least one turn from the radial direction to the axial direction. A supplementary means 40 for a compressor housing includes a ring-shaped cavity 43, and an external supply pipe 44 for a gaseous medium which communicates with the cavity. A plurality of blow-in apertures 55 are provided in a region of a housing wall 51 on the end face side of the muffler, and these blow-in apertures face the axial direction and connect the ring-shaped cavity 43 to the passage of the muffler. <P>COPYRIGHT: (C)2012,JPO&INPIT |
