摘要： A pressure accumulator comprises an accumulator housing (2) in which a movable separating element (30) fluid-tightly separates a gas chamber (16) filled with a working gas from a fluid chamber (28). The pressure accumulator is characterized in that a monitoring device (50, 54) is provided which supplies an optical signal in the event of a malfunction affecting the sealing effect of the separating element (30).

摘要： A hydraulic accumulator (14) is equipped with a novel shut-off valve. The shut off-valve includes a valve body (21) having a cylindrical hollow with a valve seat (37) surrounding one end. The main piston (24) including a piston head has a central opening (30) and is slidably mounted within the cylindrical hollow of the valve body. A poppet valve (22) has a valve head which mates with the valve seat and a valve stem which extends through the central opening of the piston to guide axial movement of the poppet valve relative to the piston. A spring (23) is mounted between the valve head and the main piston head for urging the valve head away from the piston head. A control valve (27) moves the piston relative to the valve body between open and closed positions responsive to signals from a computer (72) which signals valve closing upon determination that flow rate through the valve exceeds a maximum period. The spring between the poppet valve head and the piston head exerts a force approximately equal to that of a pressure drop across the poppet valve at a predetermined maximum flow rate.

摘要： The invention relates to a hydraulic accumulator, especially a piston-type accumulator, comprising an accumulator housing (10) as well as at least one gas chamber (12) that is arranged therein and a fluid chamber (14) which are separated from each other via a separating element (16), particularly in the form of a piston. One free end of the accumulator housing (10) is sealed via a valve block (24) that is provided with a ball valve (28) which opens or blocks a fluid-guiding path (30) from the interior of the accumulator housing (10) towards the outside in the open position or closed position thereof such that the ball valve forms an integral part of the accumulator housing via the valve block and is thus accommodated in a compact manner within the hydraulic accumulator solution, also resulting in a reduction of the free fluid paths and therefore a reduction of tubing.

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.
