TURBOCHARGER NOISE DEFLECTOR

摘要

A turbocharger having a bypass port compressor, with a center channel that flows directly into the compressor wheel (50), and an annular channel (72) which acts as a bypass and provides flow either into or out of the compressor wheel, with an inner deflector (90) having at least a first surface substantially perpendicular to the annular channel and extending radially into the annular channel, and at least a second surface substantially parallel to the annular channel and extending axially along the annular channel, such that line-of-sight transmission of sound from the annular channel is eliminated, and sound waves are instead dampened or canceled, reducing noise emissions from the compressor.
