Abstract

A compressor assembly is disclosed. The compressor assembly may have a compressor housing and a compressor impeller disposed within the compressor housing. The compressor impeller may have a hub extending from a hub front end to a hub rear end and an exducer blade disposed on the hub adjacent the hub rear end. The compressor impeller may further include a hub extension extending outward from the hub rear end. The compressor assembly may also have an impeller cap disposed on the hub extension. Further, the compressor assembly may have a windage seal disposed on the impeller cap. The windage seal may be separated from a blade rear surface by an axial gap. In addition, the compressor assembly may have a compressor diffuser disposed within the compressor housing. The compressor diffuser may have a diffuser inner surface separated from an outer rim of the exducer blade by a radial gap.
