The subject-matter of the invention is a device for aeration balance inside vaults or tombs. It is characterised by the combination, which forms an integral unit, of on the one hand an admission chamber 6 containing a fluid 7 constituting a non-return valve receiving the outside air directly via a plunger tube 4 and distributing it at its opposite end into the sealed-off area via a conduit 9 placed above the liquid, and on the other hand of an evacuation chamber 11 provided with the same elements in reverse, evacuating the gases from the inside of the area towards the outside by way of a purifying fluid 16. It is intended not only to ensure a distribution of clean air taken from the outside, within the sealed-off areas of interment, vault and tomb, but also an evacuation of the excess pressures from the inside towards the outside. <IMAGE> |
