Abstract
An accumulator system includes a housing, including a motor housing including an electric motor, a function chamber and an anti-rotating chamber each coupled to the motor housing, a balance chamber, a transfer chamber disposed between the anti-rotating chamber and the balance chamber, a shaft configured to move axially within the function chamber, the anti-rotating chamber, and the transfer chamber, a first piston coupled to a first end of the shaft, a second piston coupled to a second end of the shaft, and third piston configured to separate the transfer chamber from the balance chamber. The electric motor is coupled to and drives the shaft to alternatingly compress working fluid with the first piston in the function chamber to drive the working fluid out of the function chamber, and compress transfer fluid with the second piston in the transfer chamber to drive the transfer fluid out of the transfer chamber.
