Abstract
Methods and systems for storing kinetic energy in a fluid-base power circuit. A regenerative control valve manifold diverts fluid flow from a hydraulic device performing a first operation into an accumulator. The accumulator stores a fluid volume sufficient to perform a second operation. The regenerative control valve manifold connects the accumulator to the power circuit providing a fluid flow and charge pressure sufficient to perform the second operation.
