Abstract
A hydraulic energy retention system includes a body with a piston separating a hydraulic fluid from a pressurized gas, a discharge port in fluid communication with the hydraulic fluid, and a stop operable to an engaged position to block movement of the piston past the stop and toward the discharge port. The hydraulic energy retention system may be implemented with a hydraulic fluid reservoir, such as a bootstrap reservoir.
