摘要： An impeller assembly is for a fluid machine, such as a compressor, and includes a first, main body and a second body. The main body includes a first section providing at least a substantial portion of either an impeller disc or an impeller cover and a second section spaced generally axially from the first section and providing a portion of the other one of the disc or the cover. A plurality of integrally formed blades extend between and connect the main body first and second sections such that the main body is generally of one piece construction. A plurality of flow channels are defined between the blades and a plurality of access openings extend into the flow channels. The second body provides a remainder of the disc or cover and is attachable to the main body to substantially form an impeller and to close all of the access openings.
