Abstract
A refrigeration circuit comprising serially arranged low and high stage compressors, a condenser, an expansion device, and an evaporator. The circuit also includes by-pass means connecting a low pressure line with the high stage compressor for conducting refrigerant vapor therebetween to by-pass the low stage compressor, and a quench line connected to the by-pass means for conducting liquid refrigerant thereto. A check-quench valve is located at the intersection of the by-pass means and the quench line. The check-quench valve has a quench position blocking the by-pass means and opening the quench line, and a by-pass position opening the by-pass means and closing the quench line.
