Abstract (en)
[origin: WO2014154984A1] The invention relates to a device which comprises a sealed enclosure (18, 22, 26, 28) containing a fluid, (38) the liquid phase of which is in equilibrium with the vapour phase, the enclosure (18, 22, 26, 28) being divided into a first space (18, 22, 26) and a second space (28) communicating via a passage (32, 34), the second space (28) comprising a vessel (36) in communication with the passage (32, 34) and capable of containing the fluid in liquid phase when the device is in a predetermined position (D). The second space (28) contains a non-condensable gas (40) that is not soluble in the liquid phase of the fluid (38), and said gas (40) and the second space (28) are selected such that, when the device is placed in the predetermined position (D), said gas (40): at least partially fills the passage (32, 34) when the temperature of the gas is lower than a first predetermined temperature (Τlim max) of the temperature range; and clears the passage (32, 34) when the temperature of the gas is higher than the first predetermined temperature (Τlim max) of the temperature range.
