This invention relates to a dispensing arrangement for pressurized fire suppression agent, which may be used to extinguish fires or explosions within very short time periods. The invention comprises a housing having a cylindrical bore defining a flow path that is blocked by a piston. The piston is held in place by steel balls, which protrude through cylindrical bore, and which are in turn held in place by an annular collar. The annular collar can slide between a secured position, in which the steel balls are held so that they protrude through the cylindrical bore, thus preventing movement of the piston; and a released position in which the steel balls are received into an annular channel along the inner surface of the annular collar. In the released position, the balls do not protrude into the cylindrical bore and the piston is released, thus releasing the pressurized fire suppression agent. |
