Abstract
An accumulator system is configured to store energy and includes an accumulator having a liquid chamber coupled to a liquid port and an air chamber coupled to an air port. The liquid chamber and the air chamber are separated by a moveable isolation barrier. An air motor/compressor coupled to the air port is configured to receive a mechanical input and responsively pump air into the accumulator, and to receive pressurized air from the air port and responsively provide a mechanical output. A liquid reservoir is coupled to the liquid port to receive liquid from the liquid chamber as air is pumped into the air chamber and to provide liquid to the liquid chamber as air is removed from the air chamber.
