Abstract
A prewhirl construction for the compressor of a turbocharger. The periphery of the compressor input opening is provided with a plurality of slanted spin vanes which impart a tangential velocity to air entering the compressor. The air is thus provided with a velocity component similar to the compressor's impeller velocity. The input duct to the compressor carries a butterfly valve whose setting controls the amount of air entering through the peripheral spin vanes. The operating surge line is moved so as to increase the flow range of the compressor.
