CRYOGENIC VESSEL WITH AN ULLAGE SPACE VENTURI ASSEMBLY

摘要

A cryogenic vessel (10) includes a first, outer vessel assembly (12) having an outer vessel (18) and a liquid fill line assembly (16) and a second, ullage space vessel (14) having a bottom and disposed within the first, outer vessel (18), adjacent to the top of the first, outer vessel (18). The liquid fill line assembly (16) has a venturi assembly (50) adjacent the bottom of the ullage space vessel (14). The venturi assembly (50) is structured to create a low pressure zone, relative to the ullage space vessel (14), during a fill procedure whereby, during a fill procedure, fluid is drawn from within the ullage space vessel (14) into the fill line assembly (16).
