Summary:A fire extinguisher (50, 50~, 50~) comprises a container (10, 10~) that holds a fire-extinguishing substance and that has a container jacket (12, 12~) closed at both ends, and a piston (20, 20~) which is axially displaceable in the container jacket and which separates a space (22, 22~) for fire-extinguishing substance from an expansion space (24, 24~) in the container. According to the invention, an inner compressed-gas chamber (26, 26~) provided in the container (10, 10~) is spatially separate from the expansion space and serves for controlled pressurizing of the expansion space (24, 24~). The piston (20, 20~) is arranged such that it can be displaced along the compressed-gas chamber (26, 26~).
