对一台高性能单级GM型脉管制冷机的直流流量抑制和制冷特性进行了实验研究。实验研究了双进气口引入的直流气流对制冷机制冷性能的影响。在本实验中，成功地采用了两个流向相反的平行针阀结构，即双阀结构，而不是传统的单阀结构作为双进气口，以减少直流流量。在双阀结构下，RW2和CP4000压缩机的最低温度分别达到18.4K和14.7K，30K时的制冷功率分别为11.5W和29.5W。
Experimental investigation on DC flow suppression and refrigeration characteristics of a high-performance single-stage GM-type pulse tube cooler has been undertaken. The influence of DC flow induced by the introduction of double-inlet on the refrigeration performance of the cooler is experimentally examined. Two parallel-placed needle valves with opposite flow direction called double-valved configuration, instead of conventional single-valved configuration as the double-inlet is successfully used in this experiment to reduce the DC flow. With a double-valved configuration, 18.4 K and 14.7 K (minimum temperature) are reached driven by RW2 and CP4000 compressor, respectively, and 11.5 W and 29.5 W (cooling power) at 30 K are obtained as well.
