  • Patent number: 10006669
    Abstract: A cryogenic refrigerator includes a refrigerator having a cylinder and a displacer movably arranged in the cylinder. The displacer is operative to provide intake of an operating gas into the cylinder and exhaust of the gas out of the cylinder. The refrigerator includes a compressor for compressing the operating gas. The compressor includes a low-pressure side to receive the gas exhausted from the cylinder and a high-pressure side to discharge the gas compressed in the compressor into the cylinder. The refrigerator includes a medium-pressure buffer volume connected to a high-pressure side or a low-pressure side of the compressor. The compressor adjusts a pressure of the buffer volume. The buffer volume is also connected to the cylinder.
