COMPRESSOR DIFFUSER AND SHROUD FOR A MOTOR DRIVEN COMPRESSOR

摘要

An aspect includes a compressor diffuser and shroud for a motor driven compressor assembly. The motor driven compressor assembly includes a first stage compressor and a second stage compressor. The compressor diffuser and shroud of the first stage compressor includes a diffuser portion, a compressor inlet portion, and a shroud portion. The diffuser portion includes a diffuser portion outer lip having a first sealing lip outer diameter to provide a first sealing interface to a first stage compressor housing. The compressor inlet portion includes an inlet portion outer lip having a second sealing lip outer diameter to provide a second sealing interface. The shroud portion includes a curvature between the diffuser portion outer lip and the inlet portion outer lip to align with a first stage compressor rotor, where a ratio of the first sealing lip outer diameter to the second sealing lip outer diameter is between 1.622 and 1.628.
