| 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.
