Abstract

An expandable accumulator and reservoir assembly includes a reservoir defining an interior chamber containing working fluid therein and an expandable accumulator. The expandable accumulator includes an inner layer and an outer layer at least partially surrounding the inner layer. The inner layer includes a higher fracture strain than the outer layer. The accumulator is at least partially positioned in the reservoir and at least partially immersed in the working fluid contained within the interior chamber. The accumulator is configured to exchange working fluid with the reservoir.
