Claim Text:
1. A refrigerant system comprising: a compressor, a condenser downstream of said compressor, an expansion device downstream of said condenser, and an evaporator downstream of said expansion device, and a refrigerant circulating from said compressor to said condenser, through said expansion device and said evaporator and then returning to said compressor; a control controlling a system component to reduce the amount of liquid refrigerant to pass through the compressor; said system component is a suction modulation valve; said control throttles said suction modulation valve toward a closed position to reduce mass flow when conditions indicate there might be an undesirable amount of liquid refrigerant to pass through the compressor; and a discharge valve is positioned intermediate said condenser and said compressor, and said discharge valve is throttled in combination with said control controlling said suction modulation valve.
