Abstract
A cryogenic liquid delivery system includes a storage tank holding a quantity of a cryogenic liquid such as liquid oxygen and a vapor space. A compound, two-part dip tube includes an inner liquid delivery tube and an outer tube which is sealed to allow liquid cryogen to be delivered to a vaporizer only via the liquid delivery tube. The vaporizer communicates with the vapor space in the tank via an aperture in the outer tube, above the level of the liquid cryogen and the seal.
