## CPC

- A62C 13/66: with extinguishing material and pressure gas being stored in separate containers
- A62C 13/76: Details or accessories
- A62C: FIRE-FIGHTING (fire-extinguishing compositions, use of chemical substances in extinguishing fires A62D1/00; spraying, applying liquids or other fluent materials to surfaces in general B05; alarm arrangements G08B, e.g. fire alarms actuated by smoke or gases G08B17/10)

## Abstract

A protective device with a pressure tank (1) includes an elastic extinguishing agent balloon (3) filled with an extinguishing agent (23) and a propellant, where the elastic extinguishing agent balloon (3) borders onto at least one elastic component (32) and this elastic component is fluid permeable. The upper part of the elastic extinguishing agent balloon (3) is formed as a sealing ring. The device has the advantage that when it is used in mobile and stationary objects, where vibrations and other forces act on the extinguishing device, a high degree of operational safety of the extinguishing device can be assumed, that makes it possible to discharge almost 100 percent of the extinguishing agent without any malfunctioning. The operation of the extinguishing device is also temperature independent so that no additional safety measures are required in the case of a change in the spatial attitude of the pressure tank.

## Claims

### Claim 1

A device comprising;
a pressure tank (1) in which an elastic extinguishing agent balloon (3) filled with an extinguishing agent (23) and a propellant gas (24) surrounding the elastic extinguishing agent balloon (3) are arranged,
the elastic extinguishing agent balloon (3) bordering onto an elastic fluid permeable component (32), wherein the elastic fluid permeable component (32) is arranged opposite an opening of the pressure tank (1) on a floor or on a fluid permeable part (28) of the pressure tank (1), the elastic fluid permeable component (32) fixating the elastic extinguishing agent balloon (3).

### Claim 2 (depends on 1)

The device according to claim 1, wherein the elastic extinguishing agent balloon (3) is bounded by a stabilizer (2).

### Claim 3 (depends on 1)

The device according to claim 1, wherein part of the elastic extinguishing agent balloon (3) is formed as a seal (11).

### Claim 4 (depends on 3)

The device according to claim 3, wherein the seal of the extinguishing agent balloon (3) together with the pressure tank (1) and a closure separates two compressed fluids (24, 23) from each other and seals from a pressure-less atmosphere.

### Claim 5 (depends on 3)

The device according to claim 3, wherein the seal (11) is formed as an O ring.

### Claim 6 (depends on 1)

The device according to claim 1, wherein the pressure tank (1) is closed by means of a control device (21) in which a differential piston (9) is situated and where an extinguishing line (15) and a control line (14) are arranged on the control device (21).

### Claim 7 (depends on 6)

The device according to claim 6, wherein the extinguishing agent (23) is released by a drop in pressure in the fluid-filled control line (14).

### Claim 8 (depends on 7)

The device according to claim 7, wherein an operating pressure in the pressure tank (1) is identical to that in the fluid-filled control line (14).

### Claim 9 (depends on 1)

The device according to claim 1, wherein the pressure tank (1) is closed by means of a solenoid valve (33) and the extinguishing agent (23) is released by an electric signal to the solenoid valve (33).

### Claim 10 (depends on 7)

The device according to claim 7, wherein heat sensors (13) and a manual release (17) are arranged in the control line (14) and extinguishing nozzles (12) are arranged in the extinguishing line (15).
