Abstract

A compressor having a housing along with a wheel including a hub and a plurality of impellers defining flow channels is disclosed. The hub forms a flow surface that defines a concave surface-curve from an inducer end to an inflection point, and a convex surface from the inflection point to an exducer end of the flow surface. The hub forms a back-disk surface including a circumferential edge-channel inset from and surrounding a central portion. The housing includes a conical inner-diffuser wall surrounding a circular inset wall. The central portion of the back-disk surface is received by the conical inner-diffuser wall, while the exducer end of the flow surface extends radially outward to be axially over an inner portion of the inner-diffuser wall.
