DISPENSING SYSTEM WITH INTERIORLY DISPOSED AND EXTERIORLY ADJUSTABLE REGULATOR ASSEMBLY

摘要

A fluid storage and dispensing system (10) including a vessel (12) for holding a fluid, an adjustable set point pressure regulator (42) in the ineterior volume of the vessel (12), a dispensing assembly in fluid flow communication with the regulator for dispensing fluid at a pressure determined by the set point regulator, and an adjusting assembly (52) exterior to the vessel for in situ adjustment of the set point of the internally disposed regulator (42). By such arrangement, fluid storage and dispensing operations can have respectively differing regulator set point pressures, as for example a sub-atmospheric pressure set point for storage and a super-atmospheric pressure set point for dispensing.
