A fire fighting apparatus has releaseable spray heads, a tube system for leading extinguishing medium from an extinguishing medium source to the spray heads, and at least one drive gas source for driving the extinguishing medium at a high pressure via the tube system to the spray heads. The at least one drive gas source is coupled to a long tube constituting part of the tube system in such a way that the long tube together with the at least one drive gas source constitutes an hydraulic accumulator. The volume of the extinguishing medium source is constituted by the volume of the long tube at least to a substantial extent.

A fire fighting apparatus according to claim 2, characterized in that a stop/opening valve (13 to 15; 13′ to 15′) for closing and opening the flow of extinguishing medium in the tube (2; 2) is arranged between individual drive gas sources (9 to 12; 9′ to 12′).4. A fire fighting apparatus according to claim 2, characterized in that the tube (2; 2′) is divided into a number of main sections (1), each containing at least one of the second drive gas sources.5. A fire fighting apparatus according to claim 4, characterized in that the drive gas sources are constituted by nitrogen bottles (9; 9′) having a pressure of 30 to 400 bar.6. A fire fighting apparatus according to claim 4, characterized in that the main sections (1) comprise a number of zones (A), each of them containing a group of the spray heads (5b to 5e, 6b, 6e′; 5b′ to 5e′).7. A fire fighting apparatus according to claim 6, characterized in that the release means (8a, 8b) are arranged along the tube (2;2′) within the zones (A) for releasing a group of the spray heads (5b to 5e, 6b to 6e); 5b′ to 5e′) belonging respectively to the zones.8. A fire fighting apparatus according to claim 7, characterized in that each group of spray heads (5b to 5e, 6b to 6e; 5b′ to 6e′) contains a valve (7b to 7e; 7′) to control at least one spray head belonging to the group (5b to 5e, 6b to 6e; 5b′ to 5e′).9. A fire fighting apparatus according to claim 1, characterized in that the tube system (2, 3a to 3e, 4a to 4e; 2′, 3a′, 3e′) follows a longitudinal direction of a tunnel (1; 1′).10. A fire fighting apparatus according to claim 9, characterized in that the spray heads comprise first spray heads (5b to 5e) arranged in an upper part of the tunnel (1) and second spray heads (6b to 6e) arranged in a lower part of the tunnel, whereby the first spray heads are arranged to spray mainly in the opposite direction with respect to the second spray heads.11. A fire fighting apparatus according to claim 1, characterized in that the spray heads (5a to 5e, 6b to 6e; 5a′ to 5e′) spray mist.12. a fire fighting apparatus according to claim 1, characterized in that the extinguishing medium is water-based liquid.13. A fire fighting apparatus comprising a plurality of spray heads (5a to 5e, 6a to 6e; 5a′, 5b′ to 5e′), a tube system (2, 3a to 3e, 4a to 4e; 2′, 3a′, 3e′) for leading extinguishing medium to the spray heads, at least one drive gas source (9 to 12; 9′ to 12′) for driving the extinguishing medium at a high pressure via the tube system to the spray heads and release means (8a, 8b) for activating at least one of the spray heads, wherein the at least one drive gas source (9 to 12; 9′ to 12′) is coupled to an extinguishing medium source which consists essentially of a long tube (2; 2′) which has a length of at least two hundred meters and constitutes part of the tube system.14. A fire fighting apparatus comprising a plurality of spray heads (5a to 5e, 6a to 6e; 5a′, 5b′ to 5e′), a tube system (2, 3a to 3e, 4a to 4e; 2′, 3a′, 3e′) for leading extinguishing medium to the spray heads, at least one drive gas source (9 to 12; 9′ to 12′) for driving the extinguishing medium at a high pressure via the tube system to the spray heads and release means (8a, 8b) for activating at least one of the spray heads, wherein the at least one drive gas source (9 to 12; 9′ to 12′) is coupled to an extinguishing medium source which consists essentially of a long tube (2; 2′) which has a length of at least about 1 km and constitutes part of the tube system.
