Abstract
An expandable accumulator and reservoir assembly includes a housing defining an interior chamber configured to contain a working fluid therein. An expandable accumulator is positioned at least partially within the housing. The expandable accumulator includes at least one flexible member configured to be at least partially immersed in the working fluid contained within the interior chamber. A rigid support member is positioned in the interior chamber and outside of the expandable accumulator. The rigid support member has at least one aperture to allow passage of the working fluid. An additional flexible member is positioned outside the rigid support member and has perimeter portions sealed to the outside of the rigid support member. The additional flexible member defines a flexible boundary between a primary reservoir inside the additional flexible member and a separate secondary reservoir outside the additional flexible member.
