Abstract
A device, particularly for compensating the internal and external pressures in a double-glazing unit, such double-glazing units comprising a frame which supports two sheets made of at least partially transparent material, a chamber being formed between the two sheets and being adapted to provide an air space for thermal and acoustic insulation. The device comprises a duct which connects the inside of the chamber to the outside environment and is shaped so as to form two siphons arranged in series, a first siphon, located towards the chamber, having a higher head than a second siphon, located towards the outlet of the duct into the outside environment, the device further comprising elements for absorbing the moisture of the air contained in the portion of duct between the siphons.
