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.

摘要： A higher temperature end of a pulse tube is connected to a lower side of a supporting member so as to position at a lower temperature end of the pulse tube at a lower position. Such a structure prevents free convection of a working gas in the pulse tube, which is a cause of reduced refrigerating efficiency. If a cold head is desired to be contacted with a member to be cooled down from its (lower) side, such a need can be satisfied by mounting the cold head on the lower temperature end of the pulse tube (a lower temperature end of a regenerator).

摘要： A rotary valve unit in a pulse tube refrigerator is quiet, and has high durability and improved refrigeration efficiency by restricting the generation of unidirectional flow. A center hole is formed on a sliding plane side as a recessed space in the sliding surfaces between the sliding plane and another sliding plane. Since the second center hole is in communication with a low pressure input port via a communication passage, the leakage between the sliding surfaces of the sliding planes can be introduced to the low pressure input port with low pressure.
