Abstract
A double acting accumulator system includes a housing including an actuator housing, a first piston housing coupled to the actuator housing, a second piston housing coupled to the actuator housing, a shaft configured to move axially within the first piston housing and the second piston housing, a first piston coupled to a first end of the shaft, a second piston coupled to a second end of the shaft, an electric actuator configured to couple to and drive the shaft to alternatingly compress fluid with the first piston in the first piston housing and the second piston in the second piston housing to drive fluid out of the respective first piston housing and the second piston housing, and a plurality of anti-rotation shafts configured to block rotation of the shaft.
