STORAGE DEVICE BASED ON SURFACE TENSION

摘要

The invention relates to a storage system comprising: an enclosure containing a liquid and a pressurant gas and a liquid-expelling device comprising a structure made up of rigid elements which define a grid-like interior surface forming a gas barrier and which delimit a central outlet passage and gaps whose width increases as a function of the distance to the central passage from a minimum value selected for the said gas barrier, to a maximum value selected so as to prevent the liquid contained inside the structure from being expelled into the enclosure as long as the acceleration does not exceed a given threshold, said structure constituting a buffer-tank from where the liquid can be expelled through the central passage under the effect of the gas at every phase of utilization and which is re-filled with liquid contained inside the enclosure by means of a feeding device which converges to a liquid input provided in the structure.
