Thus, intake air pressurized by a low pressure stage compressor 21 and bypassing a high pressure stage compressor 41, and intake air bypassing the low pressure stage compressor 21 and pressurized by the high pressure stage compressor 41 are introduced to the internal combustion engine 10.

摘要： PROBLEM TO BE SOLVED: To obtain a compressor increasing the compressor efficiency when the flow rate of air flowing into an impeller-housing chamber is small, and inhibiting deterioration of the compressor efficiency when the flow rate is large.SOLUTION: A compressor part 30 includes a diffuser chamber 54, a scroll chamber 56 and a diffuser vane 38. The diffuser vane 38 is a single vane and is arranged so that the angle θ representing the front end position on the impeller-housing chamber 52 side is in the range of 0°≤θ≤180°. When the flow rate is small, since the air flow coming out of an impeller 32 is deflected to decelerate by the diffuser vane 38 and is raised in pressure, the compressor efficiency increases. Meanwhile, when the flow rate is large, since the diffuser vane 38 is the single vane and there is no throat diameter, the air flow is not choked and deterioration of the compressor efficiency can be inhibited.

摘要： PROBLEM TO BE SOLVED: To restrain a pressure loss of air having flowed into a diffuser chamber from an impeller storage chamber when air flowing into the impeller storage chamber is reduced.SOLUTION: A compressor housing 50 includes the diffuser chamber 54 provided outside the impeller storage chamber 52, a scroll chamber 56 formed outside the diffuser chamber 54, and a movable member 38 provided movably in the diffuser chamber 54 for partitioning a part of a communication portion between the diffuser chamber 54 and the scroll chamber 56 in a state placed in the diffuser chamber 54. At this time, the flow of the air flowing into the impeller storage chamber 52 is reduced, the movable member 38 is projected into the diffuser chamber 54. Since the capacity in the diffuser chamber 54 is reduced by the movable member 38, excessive diffusion of the air having flowed into the diffuser chamber 54 is restrained, so that pressure loss can be restrained.
