<P>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. <P>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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
