Claims
- 1. A fluid storage and dispensing system, comprising:a storage and dispensing vessel for holding a fluid and having a discharge port for dispensing fluid from the vessel; a thermal controller for controlling temperature of fluid in the vessel; a diffusion tube in the vessel, joined to the discharge port, and arranged for diffusion of fluid into the tube and flow from the tube to the discharge port for dispensing from the vessel; and a pressure sensor for sensing pressure of fluid dispensed from the vessel and operatively coupled with the thermal controller to selectively vary the temperature of the fluid in the vessel to correlatively vary diffusion of fluid into the diffusion tube and resultingly obtain a predetermined pressure in the fluid dispensed from the vessel.
- 2. A method of supplying fluid from a storage and dispensing vessel enclosing an interior volume for holding a fluid, and including a fluid discharge port for discharging fluid from the vessel, said method comprising:disposing a diffusion tube in the vessel, joined to the discharge port, and arranged for diffusion of fluid into the tube and flow from the tube to the discharge port for dispensing from the vessel; sensing pressure of fluid dispensed from the vessel; and varying the temperature of the fluid in the vessel in response to the sensed pressure, to correlatively vary diffusion of fluid into the diffusion tube to maintain a predetermined pressure in the fluid dispensed from the vessel.
