Abstract
A regenerative, thermodynamic cyclic process for refrigerating machines employing a high-speed compressor. During an expansion phase, a gaseous coolant is pumped by this compressor directly out of a working volume and transferred, under compression, into an intermediate tank or into a second working volume, and during a following compression phase, the coolant is pumped by the compressor out of the intermediate tank or the second working volume, while using a reversing valve actuated to operate in synchronism with a displacer movement, and returned to the first working volume of the refrigerating machine. The expended compression work is thus recovered.
