    摘要： In an oil-lubricated helium compressor unit, the adsorber can retain all of the oil that might be transferred from the compressor to the adsorber before the system shuts down. No oil is ever transferred or transferable to, for example, the expander in a GM type refrigeration system connected to the unit. The compressor itself will shut down because of a protective switch or seize for lack of oil before any oil carries outside the compressor unit. The unit and the connected refrigeration system can run for more than a selected design life before the compressor shuts down because the limit of oil in the adsorber has been reached. The adsorber can retain as much oil as might leave the compressor over the life of the system plus a safety margin of at least 25%. The adsorber need not be serviced or re-placed for the life of the system.

    摘要翻译： 在油润滑的氦压缩机单元（10）中，吸收器（34）可以在系统关闭之前保持可能从压缩机（12）传递到吸附器（34）的所有油。 没有油被转移或转移到例如连接到单元（10）的GM型制冷系统中的膨胀器。 压缩机（12）本身将由于保护开关而关闭，或者在任何油承载在压缩机单元（10）之外的情况下，因为缺油而被卡住。 由于已经达到吸附器（34）中的油的极限，在压缩机（12）关闭之前，单元（10）和所连接的制冷系统可运行超过选定的设计寿命。 吸附器（34）可以保留尽可能多的油，以使得在整个系统寿命期间离开压缩机（12）加上至少25％的安全裕度。 在系统的使用寿命内不需要对吸附器（34）进行维修或更换。

    摘要： In an oil-lubricated helium compressor unit (10), the adsorber (34) can retain all of the oil that might be transferred from the compressor (12) to the adsorber (34) before the system shuts down. No oil is ever transferred or transferable to, for example, the expander in a GM type refrigeration system connected to the unit (10). The compressor (12) itself will shut down because of a protective switch or seize for lack of oil before any oil carries outside the compressor unit (10). The unit (10) and the connected refrigeration system can run for more than a selected design life before the compressor (12) shuts down because the limit of oil in the adsorber (34) has been reached. The adsorber (34) can retain as much oil as might leave the compressor (12) over the life of the system plus a safety margin of at least 25%. The adsorber (34) need not be serviced or replaced for the life of the system.

    摘要： A two-stage pulse tube refrigerator comprises a pressure wave generator-compressor (32), first stage (16) and second stage (18) regenerators, first stage (12) and second stage (14) pulse tubes, heat exchangers (20, 22, 24, 26) and a hybrid phase shift mechanism for the first (12) and second stage (14) pulse tubes. The second stage phase shift mechanism includes double fixed orifices (40, 42) while the first stage shifter is an arrangement including one of a) 4 valves, b) 5 valves, c) 2 active buffers or d) 3 active buffers. The double fixed orifice phase shifter is located either at room temperature or is thermally connected with the first stage cold end. Two-stage pulse tube refrigerators with a hybrid phase shifter have increased second stage regenerator performance at lower temperature. Pressure drop through the valves and compressor power consumption are decreased, and losses from phase interaction between each stage are eliminated.

    摘要： A counter flow heat exchanger comprising a plurality of tubes disposed in a bundle array or tube within tube configuration to enhance heat transfer between high and low pressure tubes in the array or tube in tube configuration. Also disclosed are a method of increasing the heat transfer capacity of a tube bundle heat exchanger and a liquid helium temperature refrigerator or a reliquefier utilizing the heat exchanger.
