Abstract
A double inlet passage 70 connects a compressor 40 to remote end 53 of a vortex tube 51 that serves as the heat-rejecting heat exchanger of an orifice pulse tube refrigerator. Double inlet passage 70 includes means 3 for controlling DC flow in that passage. Fluid flows between compressor and reservoir enhance heat-rejecting effectiveness of vortex tube 51.
