    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.

    Abstract: The invention relates to an electronically controllable vehicle braking system for a motor vehicle with a cylinder/piston arrangement providing a brake fluid, which, by actuating a brake pedal, is caused to provide brake fluid acting on the brake of the motor vehicle, with the cylinder/piston arrangement being connectable with a pump arrangement and a pressure accumulator. The pressure accumulator has a housing which comprises a fluid connection for a fluid flowing into and out of the housing as well as a spring arrangement against whose force brake fluid flowing through the fluid connection is acting, with at least one part of the spring arrangement being formed by at least one part of the housing wall.

    Abstract: A vessel includes a body having a chamber normally containing pressurized gas and enclosed by a removable closure provided with a gas charging valve. Inadvertent disassembly of the closure when the chamber contains pressurized gas is precluded by a planar cover plate captively retained by the charging valve and normally masking tool-receiving members on the closure. Removal of the valve/cover plate unit initially releases a resilient seal carried by the inner face of the valve juxtaposed the outer face of the closure and subsequently progressively exposes to the atmosphere a gas bleeding passage formed in the attachment stem of the valve to gradually release all pressurized gas from the vessel chamber. The closure is only accessible for disassembly following complete removal of the unitary valve and cover plate after which all gas under pressure in the chamber has been relieved.
