Abstract
A volume ratio control system for a compressor includes a chamber formed within a housing of the compressor, where the chamber is in fluid communication with a high pressure side of the compressor, a piston disposed within the chamber, where the piston includes a cavity in fluid communication with a low pressure side of the compressor, and a biasing device disposed within the chamber and configured to enable movement of the piston in response to a pressure differential between the low pressure side of the compressor and the high pressure side of the compressor falling below a threshold value.
