摘要：

A two-stage pulse tube refrigerator in combination with a rotary valve and a valved compressor has been constructed. Its performance and the effects of the operating parameters were investigated. A minimum temperature of 11,5 K and a cooling capacity of 1.3 W at 20 K were obtained at a frequency of 4.2 Hz and a system pressure of 1.5 MPa, The 2nd-stage regenerator was only filled with lead shot.
