The object of the invention is to provide a novel fire extinguishing installation enabling effective delivery of liquid with immediate effective mixing of gas in the liquid right from the start. This is achieved by a fire fighting installation comprising a liquid source (8), a pump (1) connected to said liquid source, and a gas source (4) connected by way of a line (30) to an outlet line (2) of the pump for mixing gas with outbound extinguishing liquid delivered to spray heads (3), wherein the pump is a high pressure pump (1) having a comparatively small flow, the pump providing in the outlet line (2), when the fire fighting installation is put into operation, a pressure which corresponds to the pressure provided in the outlet line (2) by the gas source (4) and providing in the outlet line (2) a liquid pressure which adjusts to a decreasing pressure provided in the outlet line (2) by the gas source (4), for producing an extinguishing fluid in the form of a finely divided liquid mist comprising a mixture of gas and liquid. <IMAGE> |
