Abstract
A fluid storing and dispensing apparatus (10) is disclosed as having a tubular rubber bladder (12) to store a fluid, a valve (24) to regulate fluid flow from the bladder, and a support (26) that maintains the bladder in a longitudinally stretched condition to initiate desired inherent properties that provide a substantially constant fluid discharge pressure and a greater number of fill cycles prior to bladder failure than is obtainable with an unstretched bladder. Another embodiment includes a container (28) to surround and restrict the maximum diameter of the bladder to limit lateral deformation and thereby considerably increase the number of fill cycles prior to bladder failure. A system (50) for replenishing the fluid storing and dispensing apparatus is also disclosed.
