Installation for fighting fire
First Claim
1. Installation for fighting fire, comprising a hydraulic accumulator (1'"'"') which comprises at least one pressure container (2'"'"') defining a lower space (5'"'"') for extinguishing liquid and an upper space (17'"'"') for propellant gas, and a rising tube (7'"'"') positioned in the pressure container, said rising tube including a feed opening (16'"'"') for feeding extinguishing liquid into the rising tube and upwardly therein to at least one nozzle (10'"'"' to 12'"'"'), first and second vertically spaced apart side openings above the feed opening, and a throttle therein below at least one of said first and second side openings.

Abstract
An installation for fighting fire, having a hydraulic accumulator which has at least one pressure container with a space for extinguishing liquid and a space for propellant gas, a rising tube arranged in the pressure container and provided with a side opening and, at the lower part of the pressure container, a feed opening for feeding extinguishing liquid into the rising tube and further to at least one nozzle. In order to obtain an extremely small drop size of the extinguishing liquid at the final stage of the emptying of the pressure container and in order to manage with a very small amount of extinguishing liquid, the rising tube has a throttle in an area below the uppermost side opening.
