TURBOCHARGER HAVING ADJUSTABLE-TRIM CENTRIFUGAL COMPRESSOR INCLUDING AIR INLET WALL HAVING CAVITIES FOR SUPPRESSION OF NOISE AND FLOW FLUCTUATIONS

A compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The compressor housing upstream of the inlet-adjustment mechanism defines a series of acoustic cavities, and op...

description	A compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The compressor housing upstream of the inlet-adjustment mechanism defines a series of acoustic cavities, and openings are defined in the compressor housing wall leading into the acoustic cavities. The openings and cavities are aimed at mitigating noise and flow pulsation in the air inlet caused when the inlet-adjustment mechanism is adjusted to the closed position to effectively reduce the inlet diameter approaching the compressor wheel.
