| 摘要 |
The invention relates to a fire-fighting equipment, comprising a hydraulic accumulator (H) and a pressure gas source (T) connected thereto for driving liquid by means of pressure gas out of the hydraulic accumulator through an outgoing liquid tube (6) arranged in the accumulator. The object of the invention is to provide a novel equipment permitting an efficient liquid delivery from one hydraulic accumulator (H) or a plurality of hydraulic accumulators (H, H'), by mixing gas efficiently in the liquid immediately from the beginning. This is achieved in such a way that the outgoing liquid tube (6) comprises a throttling (11) and that to the liquid tube (6), after said throttling (11), is connected a throttled gas inlet (13) preferably from the same pressure gas source that is connected to the hydraulic accumulator (H) for driving liquid out of this accumulator.
