    Abstract: A vehicle brake system has a gas pressure accumulator (10) comprising a housing (12), the interior of which is divided by metal bellows (16) into a gas-sensed gas chamber (20) and a fluid chamber (22). Via a feed line (24) a fluid may be supplied under pressure to and removed from the fluid chamber (22), wherein provided between the fluid chamber (22) and the feed line (24) is a valve arrangement (74), which closes when the pressure in the feed line (24) drops below a minimum value and opens when the pressure exceeds the minimum value. To increase the operational reliability of the gas pressure accumulator (10), the valve arrangement (74) closes when the pressure in the feed line (24) exceeds a maximum value and opens when the pressure drops below the maximum value.

    Abstract: A fluid accumulator (1), preferably for use in connection with a hydraulic system which is to receive relatively large quantities of working fluid in a short period of time comprises a housing (2) and a piston (3) arranged therein, which separates the working fluid, especially an oil, from an expanding fluid, especially a gas, and which easily can be displaced in the housing (2) in dependence of the pressure conditions arising from the hydraulic system by being adapted to float freely between the two fluid phases by providing between the outer surface of the piston (3) and the inner wall of the housing (2) a space (7c) in which the two fluid phases can communicate freely and which at the same time provides a fluid sliding layer so that the piston (3) can quickly and effectively move between its various positions. The piston (3) has the shape of a cylindrical cup having a relatively large extension in the axial direction and having its opening facing upwardly. The unique structure of the piston (3) makes it possible to work under pressure conditions in the range of 200-350 bars.

    Abstract: The hydropneumatic accumulator disclosed herein comprises a rigid upright vessel, the mouth of which is at the bottom, containing an inverted bag-like bladder. The mouths of the vessel and of the bladder are sealed to one another. The bladder extends upwardly within the vessel interior and divides the same into inner and outer compartments which respectively contain an incompressible liquid medium and a compressible gaseous medium. To protect the bladder from damage by uncontrolled flexure of its wall in response to variations in the relative pressures within the inner and outer compartments, an inverted conical shape-defining member projects down into the upper closed end of the bladder and a perforated rigid shell projects upwardly into the bottom of the bladder. In addition, vertically extending circumferentially spaced stiffening ribs are formed in the wall of the bladder to hold the bladder upright.

    Abstract: An accumulator for maintaining a substantially constant pressure above ambient in a hydraulic system including a hollow cylinder which has an opening at one location to ambient and an opening at another location for communication with the hydraulic system; a piston and pushrod disposed in the cylinder for reciprocatory movement between the open locations; and a negator spring which has an arcuate end which is connected to the pushrod and an opposite end which is connected to the cylinder. A rolling diaphragm may be connected to an end of the piston and to the cylinder at a location about the piston wall.

    Abstract: An accumulator is provided, which is aimed at stabilization in mounting state of a damping member while diminishing the impact on a metal bellows. In an accumulator (100), a damping member (190) formed slidably at the inner circumferential surface of a pressure vessel (110) and suppressing the oscillation of a metal bellows (130) while keeping a gap between the metal bellows (130) and the inner circumferential surface of the pressure vessel (110) is mounted at at least one site of a plurality of annular valley parts of the metal bellows(130) including a plurality of annular crest parts and the plurality of annular valley parts alternately formed therein. In the damping member (190), a radially inward tip is fitted with the valley part, and a radially outward tip is longer than the crest part of the metal bellows radially and outwardly.
