Abstract
A compressor having plural banks of cylinders can be operated multi-stage, single stage, plural parallel single stages and, when multi-stage, with or without an economizer. One of the low stage banks of cylinders can be unloaded to reduce the first stage output during multi-stage operation or to permit operation of a single stage when the second stage is bypassed.
