  • an additional container for the extinguishing liquid is unnecessary. Thereby Space and weight in the vehicle, in particular commercial vehicle, can be saved.
  • the amount of coolant in a commercial vehicle is approximately 50 to 60 l.
  • This fire fighting can with relatively little effort by a control device, which has controlled valves, be realized.
  • the existing in the control device Valves are switched to passage in the event of a fire, which reduces the pressure in the working air delivered delivery pressure to the extinguishing liquid, in particular cooling liquid acts.
  • the valves can by a control pressure caused by the operating air be brought into the open position, so that the extinguishing liquid, in particular cooling liquid is forwarded to the sprayer.
  • the control device may be designed in such a way that the from the cooling system removed coolant directly to the spray at the fire on an open Valve or more open valves is delivered.
  • the cooling liquid in the cooling system is thereby subjected to a pressure of about 1 to 3 bar, said pressure optionally is formed by a pressure reducer from the operating pressure air.
  • a pressure obtained from an operating air pressure in the Cooling system to fill a container with coolant, for example at 1 to 2 bar, and subsequently with preferably the maximum delivery pressure of the operating compressed air, which may be about 8 to 10 bar, the cooling liquid over an open Supply valve of the sprayer for fire fighting.
  • the delivery pressure may also be from an onboard electrical Pump powered by stored energy stored at the location of the vehicle will be generated. Also, the extinguishing liquid in a separately entrained container be kept in readiness.
  • the spray nozzles may be provided with dust caps, which fall off when the Nozzle can be charged with the pressurized liquid.
  • the illustrated embodiments have a sprayer 8 in the form of several Spray nozzles in the fire hazard areas of the motor vehicle, in particular in a Engine compartment 22 are directed.
  • the spray nozzles of the spray device 8 are in particular on fire-prone engine locations, e.g. directed the turbocharger.
  • the spray nozzles of the spray device 8 can be explained via a control device to an engine cooling system 3 (Fig. 1 or Fig. 2).
  • the cooling systems 3 of the embodiments are in a known manner via cooling lines 23 with the Motor connected.
  • an operating compressed air D (FIG. 1) or D1 and D2 (FIG. 2), which are available as on-board compressed air in large quantities in several air tanks stands, uses.
  • an actuating valve 1 is provided for this purpose, which assumes the position shown in Fig. 1 in normal vehicle operation. In This position is the cooling system 3 and its radiator via an air line 24 and a Venting channel of a controllable valve 6 connected to a vent E2 and vented. A liquid line 5, which from a lower connection point 26 is placed on the radiator of the cooling system 3 to the spray device 4 is in normal operation, which is shown in Fig. 1, interrupted. This interruption is done by the valve 6, which is in its closed position. In case of fire that will Actuating valve 1 is actuated so that the operating pressure air D via a pressure reducer 2 in an upper, in particular highest point of confluence 25 with the cooling system 3 is connected.
  • the pressure reducer 2 is for this purpose via an air line 4 with the discharge point 25 connected to the cooling system 3.
  • the pressure reducer 2 is the relative high pressure of the operating pressure air D to a permissible for the cooling system 3 pressure of for example, 1 to 3 bar reduced. This pressure is sufficient to cool the coolant through the Liquid line 5 of the spray 8 zuzu discussing.
  • the pressure supplied by the operating pressure air D via an air line 7 to the valve 6, so that this from the illustrated in the figure 1 closed Position is brought into a passage position.
  • the adjustment of the valve 6 takes place against the force of a spring, through which the valve in the starting position shown in Fig. 1 is biased.
  • opening the valve 6 is a direct connection of the Coolant of the cooling system 3 via the thus opened liquid line 5 to the nozzles the spraying device 8.
  • valve 6 When closing the actuating valve 1, i. when returning the actuating valve. 1 in the position shown in FIG. 1, the valve 6 via the air line 7 and a in Actuation valve 1 provided vent passage, which with a vent point E1 is connected, vented. The valve 6 is returned to its starting position shown in FIG is returned. The liquid line 5 is thereby closed. The cooling system is then again on the located in the valve 6 vent passage and the Venting point E2 vented, as shown in Fig. 1.
  • this can be manually or electrically operated.
  • the operation can also be dependent on a fire detector (temperature detector) or a corresponding temperature-sensitive sensor.
  • a warning light can be provided on the instrument panel to the Driver to operate the valve, for example by means of a range provided To initiate push button or the like.
  • a container 27 is provided, in which in case of fire, the cooling liquid is introduced with a relatively low discharge pressure and with a high delivery pressure is passed to the sprayer 8.
  • Fig. 2 are the valves the control device in its rest position, which is present during normal driving.
  • the Actuation valve 1 is connected via a control valve 19 and a line 9 with the top of the Container 27 connected to the venting of the container 27.
  • the line 9 via a Venting channel of the actuating valve 1 connected to a vent point E1.
  • One Valve 21 is pressed by spring force in a rest position.
  • a Pressure reducer 2 to the overhead discharge point 25 on the cooling system 3 leading air line 11 prevented.
  • a part of the air duct 11, which is connected to the cooling system 3 is in the rest position of the valve 21 via a vent passage in the valve 21 with a Venting point 21 connected.
  • the cooling system 3 is vented.
  • a fluid connection which by Liquid lines 10, 12 is formed between the cooling system 3 and the container 27, interrupted.
