FLUID CONTAINER WITH INTEGRATED VALVE
Embodiments of fluid storage containers ( 312 ) comprise a displaceable electrodynamic valve ( 344 ) for selectively regulating release of fluid from the container. The fluid storage container has a port ( 342 ) and comprises means for defining a reservoir ( 330 ) for accommodating a pressurizing a fluid. A displaceable electrodynamic valve selectively opens and closes the port and thereby regulates release of the pressurized fluid from the container. In some implementations, the container has a lid ( 400 ) and the port is provided in the container lid. In other implementations, the container has a container body, and the port is provided in the container body. The displaceable electrodynamic valve ( 344 ) can take various configurations (e.g., flapper, solenoid) and various forms (e.g., piezoelectric valve) in differing example embodiments. In some embodiments a compressor ( 361 ) is provided for pressurizing the fluid, and can also take various forms.
1 . A fluid storage container comprising:
a collapsible bladder for accommodating a fluid, the bladder having a port;
a container body for at least partially enclosing the bladder;
a displaceable electrodynamic valve for selectively opening and closing the port and thereby regulating release of the fluid from the bladder; and
a compressor for applying pressure to the bladder to expel fluid from the bladder through the port when the valve is open.
2 . The apparatus of claim 1 , wherein the displaceable electrodynamic valve is a piezoelectric valve.
3 . The apparatus of claim 1 , wherein the displaceable electrodynamic valve is a valve comprised of a electroreactive polymer, a valve comprised of a electrorestrictive member, a valve comprised of a memory alloy, or a valve comprised of a magneto-restrictive element.
4 . The apparatus of claim 1 , wherein the compressor is a spring biased for applying pressure to the bladder.
5 . The apparatus of claim 1 , wherein the compressor comprises a gravity weighted member for applying pressure to the bladder.
