摘要：

Two-cascade continuously operating refrigerator with 3He adsorption pumping in the upper cascade and the condensation pumping of a working substance in the lower one is described. Main refrigeration circuits include no valves or governors; only electrical heaters and 3 valves of ancillary lines are completely adequate for the device control, which readily lends itself to automatic. For the operation with a 3He evaporation stage as the lower cascade, loading characteristics of the refrigerator and temperature drops inside moan units of the stage are presented. The 3He-4He dilution stage also may be used; its stable mode operation is provided at least for a circulation rate up to 150 μmol/s.
