The invention relates to a turbocharger compressor having an adjustable-trim mechanism including vortex reducers. A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism operable to move between an open position and a closed position. The inlet-adjustment mechanism includes a plurality of blades disposed about the compressor air inlet and located within an annular spacewithin the air inlet wall. The blades are pivotable about respective pivot points such that the blades extend radially inward from the annular space into the air inlet when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Downstream surfaces of the blades include vortex reducers that are structured and arranged to reduce a strength of an unsteady vortex generated from the radially inner edges of the blades. 本发明涉及具有包括减涡器的可调修整机构的涡轮增压器压缩机。一种用于涡轮增压器的离心压缩机包括入口调整机构，该入口调整机构可操作以在打开位置和关闭位置之间移动。入口调整机构包括围绕压缩机空气入口设置并位于空气入口壁内的环形空间内的多个叶片。叶片可围绕相应的枢转点枢转，使得
