摘要： The invention relates to a pressure accumulator, especially a pulsation damper, which comprises an accumulator housing (10) and a piston element (28) disposed therein. A bellows-type separative element (30) is supported on the piston part (28) with its one end (32) and with its other end (34) on the accumulator housing (10). Said separative element (30) separates two working chambers (26, 40) within the accumulator housing (10) from each other, especially a gas chamber (26) from a fluid chamber (40), in a fluid-tight, especially gas-tight manner. The one working chamber (26), in addition to a defined volumetric proportion of a working gas, is filled with a fluid. In this manner the working gas allows for a compression to a certain degree and thus for a dampening and smoothening of the pulsations of the fluid medium migrating to and occurring on the fluid side of the accumulator.

摘要： The invention relates to a device for damping water hammers in hydraulic accumulators, in particular in piston accumulators, which is embodied in the form of the accumulator component which operates as a throttle on a fluid flow and is inserted between internal elements (12) of the accumulator and a hydraulic network (14) to which said accumulator is connectable, the throttle being formed by at least one transfer area (24) having a predetermined cross-section in a valve element (16) which, interrupts the fluid flow up to the transfer area (24) at one of the valve positions and releases it at the other position thereof. Said invention is characterised in that the respective transfer area (24) has at least one free end and a funnel-shaped enlargement (26, 28) is oriented towards the inside of the accumulator (12) or towards the hydraulic network (14), thereby making it possible to substantially improve known damping devices in such a way that noise emission is reduced to the greatest possible extent.

摘要： The invention relates to a pressure means storage device, comprising a housing (1), the inside of which is divided into two chambers (3, 4) by a media separation element (2). The first chamber (3) is filled with a gas and the second chamber (4) is filled with a liquid. A bottom valve (6) which allows the second chamber (4) to be filled with the liquid and prevents said second chamber (4) from being completely emptied is provided in a hydraulic connection (5), the closing body (7, 40) of said valve being activated by the media separation element (2). According to the invention, the closing body (7, 40) can be moved by means of the media separation element (2 or 16) into a position in which it performs the function of a hydraulic piston. This prevents the bottom valve from being damaged and any unwanted leakage of the liquid, hereby considerably increasing the functional reliability.

摘要： 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.

摘要： Disclosed is an accumulator comprising: a pressure vessel (1); an elastic bellows (5) in which a compressed gas is sealed, an end of the bellows being fixed to an interior of the pressure vessel; a flow path (8) having an opening (8a) communicating with the interior and an exterior of the pressure vessel (1); a valve (7) connected to a movable end of the bellows (5) to operatively close the opening (8a) according to elastic motion of the bellows (5); and a hydraulic chamber (4) partitioned from a gas chamber (3) formed in an interior of the bellows (5) containing the compressed gas. The valve (7) comprises an upper surface (7a) which can cover the opening (8a), and plural circular protrusions (7b,7c) which surround the entire circumference of the opening (8a) and can closely contact the circumference of the opening (8a).

摘要： L'Accumulateur Oléo-pneumatique comporte deux enceintes séparées par une membrane souple, l'une remplie de gaz sous pression, l'autre rempliede liquide hydraulique. Les différentes pièces sont maintenues serrées les unes contre les autres par un moyen d'assemblage mis au préalable sous tension de façon à assurer une précontrainte supérieure à l'effort de séparation provoqué par la pression hydraulique maximum de séparation. Un corps cylindrique central (1) est disposé entre deux bouchons (2 et 3) qui sont reliés par au moins un tirant 6 mis préalablement en tension de façon à assurer un assemblage par serrage précontraint.
