    摘要: In a pulse tube refrigerator the refrigeration efficiency has been improved by reducing the on-off valve loss. A second space 47 in a cylinder member 41 is connected with a second high pressure on-off valve 23 and a second low pressure on-off valve 24. A buffer side on-off valve 25 is provided between the buffer space (a buffer tank 50) and the second space 47. By opening the buffer side on-off valve 25 before the second high pressure on-off valve 23 or the second low pressure on-off valve 24 is open, the pressure in the second space 47 can be the intermediate pressure. Since the pressure difference when the valves are open is decreased, the on-off valve loss can be decreased.
