ABSTRACT:
Device comprising an inlet duct for a gaseous refrigerating fluid under pressure connected to a choke opening into a fluid expansion and liquefaction chamber connecting with a refrigerating fluid discharge passage which exchanges heat with the said inlet duct, characterized in that, for the pressure range involved, the minimum opening (15) of the choke (10) and the heat exchange relationships with the inlet duct (7, 8) are such that in the minimum opening operating phase a liquefaction phase arises in the inlet duct upstream of the choke, so producing self-regulation producing the fluid flow just necessary to maintain liquefaction in the expansion and liquefaction chamber.
