Title: Surface tension storage tank

Abstract: The invention relates to a surface tension storage tank comprising a liquid outlet from where the liquid can be expelled under the action of a pressurant gas. A collector device issues into a chamber of a tubular device which also comprises a draining conduit opening at one end at the bottom of said chamber, the other end being situated higher than the first when the tank is being filled. On the side opposite its bottom, the chamber is situated close to the liquid-expelling orifice from which it is separated by an outlet gas barrier. Gas barriers are also provided at the other end of the conduit and on the level of the junction of the collector device with the said chamber.
