    Abstract: A hydraulic servo-control of a servo-controlled gearbox comprises hydraulic actuators defining chambers, a storing tank containing control fluid used by the actuators at room pressure, a hydraulic accumulator containing control fluid under pressure, a motor pump drawing the fluid from the tank and feeding it under pressure to the accumulator, and solenoid valves selectively connecting the chambers to the tank and accumulator. The accumulator includes an outer housing defining an inner cylindrical surface defining a first diameter, a piston arranged and axially slidable and mobile inside the housing and defining there a first variable-volume chamber for a gas and second variable-volume chamber for the fluid under pressure, and a limit stopper arranged at an open end of the housing, acting as a striker for the piston, and having an annular circlip defining an opening and overall second diameter approximating by excess the first diameter of the surface of the housing.

    Abstract: Some embodiments of the present invention provide an accumulator tank assembly and method in which a flexible bladder is received within an accumulator tank. The accumulator tank and the flexible bladder can each have an inlet aperture through which fluid is received within the accumulator tank assembly and an outlet aperture through which fluid exits the accumulator tank assembly. In some embodiments, inlet and outlet flanges positioned adjacent the inlet and outlet apertures of the accumulator tank are used to couple the flexible bladder to internal or external surfaces of the accumulator tank, thereby creating fluid tight seals between the flexible bladder and the accumulator tank.

    Abstract: A method of filling a pressure medium accumulator with a housing having an inner space that is subdivided into two chambers by a metallic pleated bellows used as a media-separating element. The first chamber thereof is filled with a gas and the second chamber is filled with a liquid pressure medium. The bottom valve is provided in a hydraulic port, its closing member being operable by the media-separating element. The valve permits filling of the second chamber with fluid and prevents a complete evacuation of the second chamber. To enable reliable filling of the above-mentioned chambers with corresponding media without damaging the pleated bellows, the method includes the steps of evacuating the second chamber, filling the second chamber with pressure medium and filling the first chamber with a gas.
