  • Patent number: 4201319
    Abstract: A system for dispensing a cryogen such as liquid nitrogen. The system employs two vessels containing the liquid cryogen. One serves as a pressure vessel and the other as a storage vessel. Liquid from the pressure vessel is vaporized in a ballast chamber exposed to ambient temperature, resulting in pressurized refrigerant gas. A valve selectively admits the pressurized gas into the liquid storage vessel, causing the stored liquid to be dispensed at a selected site.
