Abstract
A bladder assembly for retaining and discharging a fluid under pressure iudes a first expandable elastomeric bladder member having a first annularly-shaped base end for anchoring to a foundation and defining a first fixed end, and a first dome-shaped wall portion upstanding from the first fixed end and defining a first movable end. The assembly further includes a second expandable elastomeric bladder member disposed within and contiguous to the first bladder member, and having a second annularly-shaped base end for anchoring to the foundation and defining a second fixed end, and a second dome-shaped wall portion upstanding from the second fixed end and defining a second movable end. The first and second bladder members and the foundation are joined by fixing the first and second base ends to the foundation.
