Abstract
A scroll compressor has an economizer injection line communicating into the scroll compressor chambers. An unloader valve selectively communicates the economizer injection line back to suction. In this arrangement, the fluid ports and passages necessary to achieve the economizer injection are also utilized to achieve suction bypass unloading, and thus the compressor and system design and construction are simplified.
