A cryogenic vessel includes a first, outer vessel assembly having an outer vessel and a liquid fill line assembly and a second, ullage space vessel having a bottom and disposed within the first, outer vessel, adjacent to the top of the first, outer vessel. The liquid fill line assembly has a venturi assembly adjacent the bottom of the ullage space vessel. The venturi assembly is structured to create a low pressure zone, relative to the ullage space vessel, during a fill procedure whereby, during a fill procedure, fluid is drawn from within the ullage space vessel into the fill line assembly.

What is claimed is: 1. A cryogenic vessel comprising: a first, outer vessel assembly having an outer vessel and a liquid fill line assembly; a second, ullage space vessel having a bottom and disposed within said first, outer vessel; said liquid fill line assembly having a venturi assembly adjacent
What is claimed is: 1. A cryogenic vessel comprising: a first, outer vessel assembly having an outer vessel and a liquid fill line assembly; a second, ullage space vessel having a bottom and disposed within said first, outer vessel; said liquid fill line assembly having a venturi assembly adjacent to, and in fluid communication with, the bottom of said ullage space vessel; and said venturi assembly structured to create a low pressure zone, relative to said ullage space vessel during a fill procedure whereby, during a fill procedure, fluid is drawn from said ullage space vessel into said fill line assembly. 2. The cryogenic vessel of claim 1, wherein said fill line assembly extends through said ullage space vessel. 3. The cryogenic vessel of claim 2, wherein: said venturi assembly includes a tubular body having an inner surface with a first diameter, an outer surface, and a venturi opening; said venturi opening in fluid communication with said ullage space vessel; and said fill line assembly having a second diameter, wherein said venturi assembly first diameter is smaller than said fill line assembly second diameter. 4. The cryogenic vessel of claim 3, wherein said venturi opening is disposed adjacent to the bottom of the ullage space vessel. 5. The cryogenic vessel of claim 4, wherein: said ullage space vessel having a first and a second opening in said ullage space vessel sidewall; said second opening disposed at the bottom of said ullage space vessel sidewall; said fill line assembly further includes a first portion and a second portion; said first portion extending through said ullage space vessel and coupled to said venturi assembly; said venturi assembly extending through said ullage space vessel second opening; and said second portion coupled to said venturi assembly and extending outside of said ullage space vessel. 6. The cryogenic vessel of claim 5, wherein said second pipe portion includes a spray head. 7. The cryogenic vessel of claim 1, wherein: said venturi assembly includes a tubular body having an inner surface with a first diameter, an outer surface, and a venturi opening; said venturi opening in fluid communication with said ullage space vessel; and said fill line assembly having a second diameter, wherein said venturi assembly first diameter is smaller than said fill line assembly second diameter. 8. The cryogenic vessel of claim 7, wherein said venturi opening is disposed adjacent to the bottom of the ullage space vessel.
