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: The invention relates to a hydraulic accumulator, especially a piston-type accumulator, comprising an accumulator housing (10) as well as at least one gas chamber (12) that is arranged therein and a fluid chamber (14) which are separated from each other via a separating element (16), particularly in the form of a piston. One free end of the accumulator housing (10) is sealed via a valve block (24) that is provided with a ball valve (28) which opens or blocks a fluid-guiding path (30) from the interior of the accumulator housing (10) towards the outside in the open position or closed position thereof such that the ball valve forms an integral part of the accumulator housing via the valve block and is thus accommodated in a compact manner within the hydraulic accumulator solution, also resulting in a reduction of the free fluid paths and therefore a reduction of tubing.

Abstract: A braking system includes an accumulator positioned along the brake line between the wheel brake and a pump. The accumulator includes a cylinder defining a bore and a piston fitted within the bore. The cylinder defines an inlet and an outlet fluidically connecting the bore to the brake line. The outlet is axially spaced from the inlet and is positioned to be sealed closed by the piston when it is proximate to inlet. The accumulator stores a reserved volume of fluid that is not delivered to the pump via the outlet to thereby reduce the volume of fluid delivered to the master cylinder by the pump and prevent damage to the lip seals during ABS control.

Abstract: A hydraulic fluid reservoir comprises a body defining a variable volume chamber having one end portion movable with the level of fluid in the chamber. A biasing member acting on a traction rod extending from the movable end portion restrains movement thereof under fluid pressure. The fluid pressure in the variable volume chamber advantageously counterbalances the force of reaction in the biasing member.
