The invention relates to a fire-extinguishing system of the high-pressure gas type, in which the gaseous extinguishing agent is stored under high pressure in at least one high-pressure gas bottle (1). The bottle valve operates, with interposition of a container attachment for the extinguishing gas, as a pressure-controlled, reducing and self-regulating control valve (3). By means of a predetermined control pressure which corresponds to the pressure in the extinguishing line system (2), the pressure of the extinguishing gas is reduced from, for example, 150 to 300 bar within the control valve to, for example, 60 bar. This makes it possible to dispense with all the high-pressure components used to date between the bottle valve and the extinguishing line system. Furthermore, a computational software is no longer required.

1. A device for controlling the output pressure of a fire extinguishing system of the high-pressure gas type, comprising: at least one compressed gas container: anda pressure reduction valve, said pressure reduction valve being a pressure-controlled, self-regulating control valve comprising:a valve
1. A device for controlling the output pressure of a fire extinguishing system of the high-pressure gas type, comprising: at least one compressed gas container: anda pressure reduction valve, said pressure reduction valve being a pressure-controlled, self-regulating control valve comprising:a valve housing having an inlet opening connected to said one compressed gas container, the valve housing defining an annular high-pressure chamber,an outlet opening,a cylinder bore; anda control piston displaceable in the cylinder bore, the control piston having a side thereof defining a control pressure chamber in which a control pressure is applied such that the control piston is controlled by said control pressure, wherein the control piston is displaceable in the cylinder bore in the valve housing against the action of a spring means and the control piston and the cylinder bore are provided with cooperating passages which, in a defined position of the control piston, communicate with said annular high-pressure chamber and connect the inlet opening with the outlet opening, whereby the control valve is configured such that the high pressure of the compressed gas container exerts no displacing force component on the control piston and a pressure of the gas that flows from the outlet opening is less than said control pressure. 2. The device of claim 1, wherein the control valve is removably fastened to a valve socket which, on the one side, is adapted to be screwed to the compressed gas container by means of a threaded fitting and which, on the other side, is connected to an inlet opening of the control valve by means of a valve connector fitting insertable into a valve socket bore. 3. The device of claim 2, wherein a plunger with a valve disk is mounted in a valve socket bore of said valve socket, which plunger is displaceable by insertion of the valve connector fitting, and that the plunger is surrounded by a spring seal element between the valve disk and a ring shoulder of the valve socket. 4. The device of claim 1, wherein the cylinder bore is a part of a cylinder bushing included in the valve housing. 5. The device of claim 1, wherein the valve housing is fastened to an adapter by its inlet opening, which adapter is in turn fastened to a container valve, the container valve comprising an opening mechanism supplying the pressure of the compressed gas container to the adapter in response to a triggering pressure. 6. The device of claim 4, wherein the cylinder bushing is displaceable within the valve housing and has a cam contour that opens a container valve in dependence on the displacement position of the cylinder bushing. 7. The device of claim 6, wherein the spring means pressing against the control piston is supported at the cylinder bushing. 8. The device of claim 6, wherein the control piston abuts against an abutment of the cylinder bushing and takes the same along. 9. The device of claim 7, wherein the control piston abuts against an abutment of the cylinder bushing and takes the same along.
