A recently granted patent (Publication Number: US11892123B2) discloses a pressure vessel design that includes an elongated folded tank with a polymeric liner and an outer composite shell of resin and fiber. The tank features multiple chambers for fluid storage, a valve assembly with filling couplers, a mixing chamber, Venturi nozzles, and a suction line for fluid flow control. The design aims to optimize the temperature distribution within the chambers during the filling process, with upper chambers experiencing less temperature rise compared to lower chambers. The valve assembly includes various components such as valves, temperature sensors, solenoids, and high-pressure lines to regulate fluid flow and temperature monitoring effectively.

Furthermore, the patent details the construction of the pressure vessel, highlighting the arrangement of chambers, filling couplers, and high-pressure lines within the tank and valve assembly. The design ensures efficient fluid transfer, temperature control, and structural integrity of the vessel. By strategically placing the chambers and utilizing a polymeric liner with a composite shell, the pressure vessel can withstand high pressures and temperature differentials. The innovative features of the valve assembly, including temperature sensors and solenoids, enhance the overall performance and safety of the pressure vessel. Overall, the patented design offers a comprehensive solution for fluid storage and management, catering to various industrial applications where precise control over pressure and temperature is crucial.
