Abstract
An accumulator system includes a chamber configured to receive a first fluid, a piston configured to move within the chamber to pressurize and drive the first fluid out of the chamber, a driving shaft coupled to the piston, a screw adapter coupled to the driving shaft, a plurality of anti-rotation shafts, and an electric actuator configured to couple to the screw adapter and to rotate the screw adapter to axially move the driving shaft. The piston includes a body defining a first aperture and a plurality of counterbores. The driving shaft is coupled to the piston via the first aperture. The piston is configured to slide over the plurality of anti-rotation shafts via the plurality of counterbores.
