Abstract:
Ein Kolbenspeicher, umfassend ein Gehäuse (1), welches einen Druckraum (2) begrenzt und einen verfahrbaren Kolben (3) aufnimmt, wobei im Druckraum (2) ein kompressibles Fluid aufgenommen ist, wobei der Kolben (3) eine Gehäuseseite (4) aufweist, welche dem Druckraum (2) zugewandt ist und wobei der Kolben (3) eine Arbeitsseite (5) aufweist, welche einem Arbeitsfluid zuwendbar ist, welches den Kolben (3) bewegen kann, ist im Hinblick auf die Aufgabe, einen Kolbenspeicher anzugeben, bei welchem eine gute Dichtung und Führung des Kolbens sichergestellt sind, selbst wenn der Durchmesser des Gehäuses eine Aufweitung erfährt, wobei die Festigkeit, das Gewicht und die Kosten des Kolbenspeichers möglichst optimiert sind, dadurch gekennzeichnet, dass eine Laufbuchse (6) vorgesehen ist, innerhalb welcher der Kolben (3) verfahrbar ist.
Abstract:
The invention relates to a volume store (1) having a substantially hollow cylindrical housing (4) and a separating element (5) displaceably disposed within the housing (4), wherein the housing (4) is fixedly disposed within a hollow chamber (2) of a camshaft (3).
Abstract:
A pressure vessel assembly is provided for a pressurized fluid system The pressure vessel assembly comprises an outer casing defining an interior cavity within the outer casing, at least one fluid-pressure accumulator disposed within the interior cavity in the outer casing, and at least one isolation device disposed between the at least one fluid-pressure accumulator and the outer casing.

Abstract:
A shovel may be provided with a swing hydraulic motor, a relief valve provided on the swing hydraulic motor, and an accumulator part that supplies to the swing hydraulic motor a working oil having a pressure lower than a relief pressure of the relief valve. The accumulator part may accumulate the working oil on a braking side of the swing hydraulic motor. The accumulator part may discharge the working oil to an upstream of a main pump.
Abstract:
The invention relates to a hydraulic accumulator, especially a piston accumulator, in which a piston part (27) separates from each other two media spaces (23, 25) inside a storage housing (1), characterized in that the piston part (27) is designed as a deep-drawn part.
Abstract:
A metal bellows (110) for an accumulator (100) into which a hydraulic fluid is drawn in, has a bellows-shape in which ridge fold portions (110a) and valley fold portions (110b) are formed repeatedly with slope portions (110c) in between, wherein two of the slope portions (110c) that are adjacent to each other via a common ridge fold portion (110a) have: first slope portions (110c1) which extend from the common ridge fold portion (110a) and second slope portions (110c2) each of which extends from each of the first slope portions (110c1) such that a distance therebetween becomes much greater than the first slope portions (110c1) as the second slope portions (110c2) extend toward the adjacent valley fold portions (110b), wherein the first slope portion (110c1) and the second slope portion (110c2) are connected at an inflection point (P).
Abstract:
A bracket assembly for an accumulator is provided. The bracket assembly includes a holding element. The holding element includes a body having a front surface and two side surfaces. The two side surfaces extend from the two ends of the front surface. The holding element also includes a corner portion disposed at each of the two ends of the front surface. The corner portion is formed by an angular relationship between the front surface and each of the two side surfaces at the respective end of the front surface. The bracket assembly also includes mold member extending from the inner side of the holding element. A thickness of the mold member at the corner portion is greater than a thickness of the mold member at the front surface of the holding element.

A volume store which has a substantially hollow cylindrical housing and a separating element displaceably disposed within the housing. The housing is fixedly disposed within a hollow chamber of a camshaft.
Abstract:
The bracket comprising a rail (1) with the base and the holes (2) for fastening to the vertical support. Two pairs of guides (4) in pairs making up the slots narrowing towards the bottom to allocate the top ends of the posts (5), connected with the arched console (9) by means of the stiffeners (6,7) and the strut (8) with at least one tangential flange (10) with a hole (11) to fasten the installed equipment. It is achieved simplifying of operations and reducing time for installation on a wall and a column, simplifying mounting of pump equipment on the arched console surfaces, increasing repairability, durability, providing a possibility of dismantle, compact storing and transporting and re-installation.
