Abstract
An accumulator system that includes a housing. The housing defines a function chamber and a balance chamber. A piston moves axially within the housing. The piston separates the function chamber from the balance chamber. An electric actuator couples to and drives the piston within the housing to compress and drive a first fluid out of the function chamber.
