    Abstract: The invention relates to a vehicle braking system comprising a gas hydraulic accumulator (10) with a housing (12), whose interior is divided by metal bellows (16) into a gas-filled gas chamber (20) and a fluid chamber (22). A pressurised fluid can be supplied to and conveyed from said fluid chamber (22) via a supply line (24). A valve assembly (74) is provided between the fluid chamber (22) and the supply line (24), which closes if the pressure in the supply line (24) falls below a minimum value and opens if the pressure exceeds said minimum value. In to order to increase the operating security of the gas hydraulic accumulator (10), the valve assembly (74) closes if the pressure in the supply line (24) exceeds a maximum value and opens if the pressure falls below said maximum value.

    Abstract: The invention relates to a hydropneumatic pressure accumulator, comprising a gas chamber (7), an oil chamber (8) and a pair of metal bellows (9) which separate said chambers. The accumulator has an end plate (11) which is displaced according to volume changes in the gas chamber and oil chamber. Said accumulator is provided with a valve (15) which releases or blocks the flow of hydraulic fluid out of and into the oil chamber (8) and with a valve lifter (23) that controls the valve. During a displacement of the end plate (11), corresponding to a volume expansion in the gas chamber (7) which exceeds a predetermined maximum value, the valve lifter can be displaced by said end plate (11) into a position which blocks the valve (15). Said valve lifter (23) is connected in a fixed manner to the end plate (11) of the metal bellows (9) and the valve (15) can be blocked in two opposing directions by the displacement of the valve lifter (23).

    Abstract: The invention concerns a sphere, in particular pneumatic, comprising a rigid shell (1) and a deformable flexible membrane (2) fixed inside said shell to define two chambers whereof one at least, called pneumatic chamber (4), is destined to be filled with gas under pressure. The invention is characterised in that the sphere comprises an element (16a) whereof the mechanical properties suddenly change when the temperature reaches a predetermined value causing said element to clear a passage for the gas from the pneumatic chamber (4) through which the gas escapes, to reduce the pressure inside said pneumatic chamber. The invention is applicable to motor vehicle suspensions.

    Abstract: The invention concerns a method of measuring the pressure of a gas in a gas accumulator which can be connected up to a hydraulic-fluid circuit and in which the gas is separated from the fluid by a dividing element. When the dividing element (12) is in a given position, the gas pressure corresponding to this position is measured by a pressure sensor (40) located on the fluid side of the element. This makes it possible to check the starting pressure in a gas accumulator without affecting the operational readiness of the accumulator with regard to its associated hydraulic-fluid circuit. The invention also concerns a device for carrying out this method.

    Abstract: Provided is a hydraulic circuit capable of efficiently recovering one and the other hydraulic energies for utilization by separating and recovering the same, one hydraulic energy being extruded from a hydraulic cylinder and the other hydraulic energy being extruded in starting and stopping rotation of a hydraulic motor, so as to allow an energy density of an accumulator to increase. The hydraulic circuit has: a first accumulator (61) that accumulates pressure of hydraulic oil extruded from a boom cylinder (7cl); and a second accumulator,(125) that accumulates one pressure of the hydraulic oil relieved when the rotation of a swing motor (3m) is started and another pressure of the hydraulic oil extruded from a motor driving circuit (C) with inertial rotation of the swing motor (3m) when the rotation of the swing motor (3m) is stopped. A solenoid switch valve (127) is provided in passages (123, 129) that connect the first accumulator (61) and the second accumulator (125) so as to communicate therebetween. The solenoid switch valve (127) serves to close the passages (123, 129) when pressure is accumulated in the second accumulator (125) and to open when the pressure in the second accumulator (125) is discharged.
