    Abstract: A type IV conformable pressure vessel is provided comprising an elongated folded tank and a valve assembly configured to pass fluid into and out of an interior of the tank through first and second filling couplers directly connected to a respective first and second end of the tank. The tank has at least two chambers for the storage of fluid. The valve assembly receives fluid from an external source, selectively provides the external fluid through a Venturi nozzle into a mixing chamber, recirculates fluid from the second end of the tank into the mixing chamber, and delivers the mixture of the recirculated fluid and the external fluid to the first end of the tank.

    Abstract: A type IV pressure vessel has improved permeate gas management. The pressure vessel comprises an inner polymeric liner, a breather layer disposed on the liner, and an outer composite shell structure disposed on the breather layer. The breather layer is gas permeable, impermeable to liquids, and provides a flow passageway for gas permeating through the liner wall collected by the breather layer. The outer composite shell is formed by one or more layers of fiber of a first fiber type and resin. Gas permeating from an interior space of the liner is received by the breather layer and directed to a predetermined exit location on the pressure vessel.
