Abstract: Disclosed is an accumulator comprising a cylindrical shell including a cylindrical portion, a partitioning member for partitioning the interior of the shell into a hydraulic chamber and a gas chamber, and a port including a hydraulic fluid flow path for communicating the exterior of the shell and the hydraulic chamber. The variation of the pressure of a hydraulic fluid flowing into the hydraulic chamber is accommodated by expansion and compression of a gas in the gas chamber according to expansion and contraction of the partitioning member. The port is approximately airtightly inserted into the cylindrical portion of the shell, and is welded to an outer circumference of the cylindrical portion by means of welding.

Abstract: Hydraulic accumulator comprising an accumulator housing (1) and a diaphragm (3) located therein, which forms a displaceable partition element between a first chamber, in particular a gas chamber (7) and a second chamber, in particular a liquid chamber (5). Said membrane has several annular regions (31, 33, 35, 37, 39), interconnected by annular weak points (61, 63, 65, 67, 69, 71). The annular regions (31, 33, 35, 37, 39) have protuberances (81, 83, 85, 87, 89) on the interior face of the membrane (3) facing away from the wall of the accumulator housing (1). Said protuberances are at their thickest in the central region between neighboring weak points, thus increasing the wall thickness of the membrane (3) and are at least partially convex (91, 93), tapering off to a respective flat form towards the weak points.

Abstract: A hydraulic circuit includes an accumulator having an inflow passage which introduces a hydraulic fluid which is discharged from a hydraulic pump into a hydraulic fluid chamber and a discharge passage which discharges the hydraulic fluid from the hydraulic fluid chamber to a hydraulic actuator. The hydraulic circuit includes a valve mechanism which restricts the supply of hydraulic fluid from the hydraulic fluid chamber to the hydraulic actuator when the pressure in the hydraulic fluid chamber is less than a set pressure and which releases the restriction of the supply of hydraulic fluid to the hydraulic actuator when the pressure in the hydraulic fluid chamber is at least the set pressure. The valve mechanism may be installed inside the accumulator.

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: The present invention discloses a pressure fluid accumulator with a housing having its interior subdivided into two chambers by a media-separating element, the first chamber being filled with a gas and the second chamber being filled with a liquid, and wherein in a hydraulic port a bottom valve is provided whose closure member is operable by the media-separating element and which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber. In order to prevent a damage of the bottom valve and an inadvertent escape of fluid and, thus, ensure a considerable increase in the reliability in operation, according to the present invention, the closure member can be moved by the media-separating element to adopt a position in which it fulfils the function of a hydraulic piston.
