Discharge bypass valves open on decrease in suction pressure to maintain a minimum evaporation pressure. The flow to the bypass valve is controlled by a solenoid valve. Discharge valves are preferably piped from the compressor discharge to the evaporator inlet using an auxiliary side connector but can also be piped to the suction line.
