ABSTRACT:
A liquid delivery system which can deliver liquid from a pressurized vessel holding a volume of the liquid, out through an outlet under a controlled pressure, thereby controlling the delivery rate of the liquid. The vessel can be re-filled while controlled liquid delivery continues, either by re-filling directly into the vessel and allowing any excess of pressure to be relieved, or by using a second pressurized vessel and continuing delivery from one vessel while the other is re-filled.
