Abstract
A device for recycling a cryogenic liquid in a circuit (1) comprising at least one section (2) substantially at ambient pressure, the device comprising: a) a first cryogenic reservoir (4) to recover the liquid at the outlet of the section, this reservoir being provided with structure (4.sub.3, 6.sub.1, 7.sub.1, 8.sub.1) to pressurize the recovered liquid, b) a second cryogenic reservoir (5) continuously pressurized in operation and connected to the circuit (1) upstream of the section (2) open to the air to supply it with pressurized cryogenic liquid, the second reservoir being in selective fluid communication (16) with the first reservoir, and c) a device (12) responsive to a predetermined relationship of the levels of filling of the two reservoirs selectively to actuate the pressurization structure (4.sub.3, 6.sub.1, 7.sub.1, 8.sub.1) of the first reservoir (4) so as to transfer into the second reservoir (5) cryogenic liquid contained in the first reservoir.
