PROBLEM TO BE SOLVED: To cause a compressor belonging to a super charger and having an inducer treatment to function in the form capable of suppressing the reductions of a compressor performance and a surge suppressing effect, under the situation where gases to flow into the compressor have a swirl flow and a drift flow.SOLUTION: As an air supply device for a supercharger 33 containing a compressor 33a having an inducer treatment 34, there is used a device having a guide passage 41 for feeding a portion of the gas to be introduced into the suction port of the compressor 33a, into the compressor 33a such that the gas may flow partially along the inner face of the casing of the compressor 33a, in which the inducer treatment 34 is disposed. |
