Abstract (en)
[origin: WO2017137674A1] Cryogenic refrigeration device comprising a working circuit intended to cool a working fluid circulating in the said circuit, the working circuit comprising, arranged in series in a loop: a compression portion (3), a cooling portion (5, 6, 22, 23, 24, 26, 27), a portion with valve(s) (9), an expansion portion (10, 25, 28) and a reheating portion, in order to subject the working fluid to a recuperative working cycle comprising compression, then cooling, then expansion and then reheating to prepare for a new cycle, wherein the compression portion comprises at least one compressor (3, 20, 21) having a linear piston driven by a linear motor (1), the expansion proportion comprises at least one expander (10, 25, 28) with a linear piston, the portion with valve(s) comprises at least one regulating valve (9) linearly actuated by a linear motor and controlled in order to supply or extract the working fluid from the at least one expansion piston.
