ABSTRACT:
The fire-extinguishing device proposed includes a container, holding a gas under pressure, and a fusible hollow element designed to actuate the device. The fusible hollow element is connected to the extinguishant container in such a way that it is acted on by the compressed gas in the container. A pressure regulator is fitted between the extinguishant container and the fusible hollow element. The pressure regulator enables the device to be operated using CO.sub.2 for instance as the extinguishant, even in situations in which the ambient temperature varies widely. The fusible hollow element can also be designed as a feed line for the extinguishant. Also proposed is a valve for a fire-extinguishing device of this kind.
