CA 2175453

A method for fighting fire, in which a drive unit comprising a number of hydraulic accumulators is utilized for delivering extinguishing liquid to a number of spray heads or sprinklers. The procedure for avoiding a premature waste of propellent gas is that, at a first stage, the hydraulic accumulators (2, 3) are filled with gas, and subsequently at a second stage, the accumulators are filled with liquid, so that the liquid compresses the gas.

Procédé de lutte contre les incendies, selon lequel on utilise une unité de commande comportant un certain nombre d'accumulateurs hydrauliques et assurant l'alimentation en liquide extincteur d'un certain nombre de têtes de pulvérisation ou d'arrosage. Afin d'éviter toute fuite prématurée du gaz à propulseur, on effectue une première étape de remplissage des accumulateurs hydrauliques (2, 3) avec un gaz, puis une seconde étape de remplissage des accumulateurs avec un liquide, de sorte que le liquide comprime le gaz.
