Abstract
A compressor is provided including a housing having a suction inlet and a discharge outlet. A compression mechanism within the housing is configured to receive a vapor at the suction inlet and to provide a compressor vapor to the discharge outlet. A volume index valve is arranged near the discharge outlet. The volume index valve includes a piston positioned within a hollow chamber and configured to move between a closed position and an open position to provide a bypass flow path from an intermediate portion of the compression mechanism to the discharge outlet. The piston is configured to move within the chamber automatically in response to the operating pressure of the vapor within the compressor.
