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.
Claims7
A surface tension storage tank for liquid, comprising:
- an enclosure having a liquid outlet provided in a wall of the enclosure and through which liquid contained therein can be expelled under the action of a pressurant gas;
- a liquid collecting device extending in the enclosure;
- a tubular device situated inside the enclosure proximate the outlet and provided with a first part having a first cross-section and defining a chamber having a chamber volume communicating with the outlet and the collecting device, and provided with a second part, having a second cross-section smaller than the first cross-section, defining a draining conduit issuing at a first end into an area of the chamber opposite the outlet and which has a second end issuing in the internal volume of the tank and situated at a level of the tank more remote from the outlet than its first end;
- and
- walls forming gas barriers to separate the collecting device from the chamber at their point of communication and to separate the second end of the conduit from the internal volume of the tank.
