Abstract:
1. Automatic fire extinguishing installation comprising a plurality of diffusers ( 1 ) distributed about a locality to be protected from fire, said diffusers ( 1 ) being connected to a line ( 3 ) for the supply under pressure of a liquid adapted to extinguish a fire, fire detection means connected to automatic control means for the supply of the diffusers ( 1 ) by said supply line ( 3 ) following the detection of a fire by said detection means, and a compressed gas receptacle ( 6 ) connected by a conduit ( 5 ) to a tank ( 4 ) containing said liquid and which in its turn is connected to said supply line ( 3 ), said conduit ( 5 ) being normally closed by closure means ( 7 ) adapted to be controlled to open by said automatic control means so as to permit said compressed gas contained in said receptacle ( 6 ) to enter said tank ( 4 ) to expel said liquid toward said supply line ( 3 ) of the diffusers ( 1 ), characterized in that said diffusers are spray nozzles for said liquid associated with respective motor driven fans ( 9 ) disposed one after the other such that a motor driven fan ( 9 A) located downstream of an upstream motor driven fan ( 9 B) sucks in the greatest part of the volume between said upstream and downstream motor driven fans ( 9 A, 9 B), as well as a portion of the volume with sprayed liquid blown by said upstream motor driven fan.
