    摘要： A damping device, in particular for damping or preventing pressure surges, such as pulsations, in hydraulic supply circuits, preferably in the form of a silencer, having a damping housing (2) encompassing a damping chamber (10), wherein said damping housing (2) has at least one fluid inlet (6) and at least one fluid outlet (8) as well as a fluid receiving chamber extending between the fluid inlet (6) and the fluid outlet (8), wherein during operation of the device a fluid flow coming from the fluid inlet (6) passes through the damping chamber (10) towards the fluid outlet (8) and wherein a wall part of the fluid receiving chamber extends as a guide element (16) in at least one direction of extension transverse to the direction of the fluid flow, is characterized in that in the damping chamber (10) several guide elements (16) are provided, against which the fluid can flow and which alter the flow velocity in certain areas.

    摘要： A piston accumulator having an accumulator housing (4) and a separating piston (10), which is guided longitudinally displaceable therein, which separates two media chambers (12, 14) from each other and which has a dual sealing system (16), wherein one of the sealing systems (18) faces one media chamber (12) and the other sealing system (20) faces the other media chamber (14), wherein at the location (58) a compensation device is at least partially accommodated in the separating piston (10) between the two sealing systems (18, 20), which compensation device enables hydrostatic pressure compensation between the two sealing systems (18, 20) to prevent an undesirable pressure buildup during operation.

    IPC分类号： F15B1/24

    摘要： A hydropneumatic piston accumulator, with an accumulator housing (1) defining a housing longitudinal axis (11), in which a piston (9) is longitudinally movable between two housing covers (5, 7) positioned opposite each other. In the housing (1), the piston (9) separates a working chamber (13) for a compressible medium, such as a working gas, from a working chamber (15) for an incompressible medium, such as hydraulic fluid, and comprises at least a part (55) of a displacement measurement device continuously determining each position of the piston (9) in the housing (1). The invention is characterised in that a rod-like guide (29, 57) is stationarily positioned in the accumulator housing (1) and passes all the way through the piston (9) in each of its displacement positions in the accumulator housing (1), the piston (9) being movably guided therealong until it reaches the stop on one of the two housing covers (5, 7), and in that the piston (9) is sealed against this guide (29, 57) using a sealing device (49, 50).

    摘要： A bellows accumulator, consisting of at least one accumulator housing (2) and having a separating bellows (20) which is movably arranged in the accumulator housing (2) and has a plurality of bellows folds and separates two media spaces (8, 22) from one another, wherein the stationary open end of said separating bellows (20) is fixed to the accumulator housing (2) by means of a securing device (24) and wherein said separating bellows (20) has at its movable other end a closure part (36) having a guide device (40) by means of which the closure part (36) is guided in the accumulator housing (2), is characterized in that the closure part (36) has, in addition to the guide device (40), a sealing device which, at least in the one extended end position of the separating bellows (20), separates a fluid space (8), in which the bellows folds are arranged in the accumulator housing (2), from a fluid port (12) in the accumulator housing (2) and, at least in some of the other working positions, releases this fluid connection.

    摘要： A pressure accumulator having an accumulator housing (10) in which a movable separating element (16) separates a gas room (12) filled with a working gas from a fluid room (14) in a fluid-sealed manner, wherein a monitoring device (46) is provided, which, in the event of a fault impairing the sealing effect of the separating element (16), provides an optically discernible indication and which has an inspection window (54), through which an indicator can be observed, which is connected to the gas room (12) and whose optical properties change discernibly when wetted with the fluid, is characterized in that the indicator changing its optical properties is accommodated in a capsule (48), the capsule wall (50) of which is permeable to the passage of the fluid and which is arranged between the inspection window (54) and the separating element (16) in the accumulator housing (10).

    摘要： The invention relates to a device for determining the weight of a hydraulic accumulator (10) during the operation thereof in a hydraulic facility, where a pressurised liquid is introduced into a pressure vessel at least partially filled with a gas, said pressurised liquid compressing the gas and being stored in such a way that when it leaves the accumulator (10), hydraulic energy is emitted to the facility, and where the respective current weight of the hydraulic accumulator (10) is detected by means of a weighing device (14) applied to the hydraulic accumulator (10).
