Abstract
An apparatus can include a pressure vessel that defines an interior region that can contain a liquid and/or a gas. A piston is movably disposed within the interior region of the pressure vessel. A divider is fixedly disposed within the interior region of the pressure vessel and divides the interior region into a first interior region on a first side of the divider and a second interior region on a second, opposite side of the divider. The piston is movable between a first position in which fluid having a first pressure is disposed within the first interior region and the first interior region has a volume less than a volume of the second interior region, and a second position in which fluid having a second pressure is disposed within the second interior region and the second interior region has a volume less than a volume of the first interior region.
