The invention, "disposable assembly of fire extinguisher cylinder and valve", makes it possible to manufacture both steel and plastics assemblies, or to combine these materials in alternation, in four possible variations, the most preferred embodiment being with a steel cylinder and a plastic valve, and to manufacture the assembly in various sizes, models, aims, categories and fire extinguishing powers. The invention forms a disposable assembly containing seven safety devices in the two elements, the valve and the cylinder, made of the same material, forming an integral body in each of these elements. The invention makes more simple and simultaneous operation possible, both during the coupling action and during the opening or breaching action, which render the assembly unusable and disposable. |
