  "abstract": "An electro-hydrostatic actuator having a main circuit, a charging circuit and four different operating quadrants uses return flow from the main circuit to the charging circuit to charge an accumulator of the charging circuit during an actuator-retracting pumping quadrant and an actuator-retracting motoring quadrant of the actuator's four different operating quadrants. A charged state of the accumulator is used to deliver compensatory flows to the main circuit during at least some instances of an actuator-extending pumping quadrant and an actuator-extending motoring quadrant of the four different operating quadrants.",
