Definitions

  • the subject of this invention is a device for extinguishing fires.
  • a fire extinguishing device in which an ejector distributes the extinguishing body or fluid in the form of a conical sheet, of suitable apex angle, enabling the burning zone to be encircled and to be progressively reduced by the suitable operation of the ejector.
  • This operation of the ejector may consist either of a variation of the height of the ejector above the burning zone or of a variation in the angle of projection of the ejector in such a way as to obtain the desired variation of the zone encircled.
  • the extinguishing device comprises in combination with a reservoir containing an extinguishing body or mixture of extinguishing bodies, in a suitable form or physical state, fluid, liquid or power under appropriate pressure, one or more ejectors having one or more directional mouthpieces suitably grouped or otherwise, capable of ensuring that the projected body, in a fluid, liquid, powdered, mixed or combined state, will be distributed in the form of a conical sheet, having a constant or variable apex angle, with the object of thus forming by means of the ejector a continuous enveloping surface, sensibly airtight, of the projected body, susceptible of being used for extinguishing the fire prevailing in a certain zone, by separation or isolation of this zone from the exterior surroundings.
  • Fig. 1 shows in section an ejector embodying the present invention and which can distribute an extinguishing body or fluid in the form of a sheet with variable apex angle
  • Fig. 2 is a section of the same ejector on line II-II of Fig. 1,
  • Fig. 3 is a variation of Fig. 1 permitting automatic variation of the apex angle.
  • Fig. 1 an ejector which can distribute the extinguishing fluid in the form of a conical sheet with variable apex angle.
  • the nozzle 9 comprises a cylindrical exit orifice IS in which can be displaced a core I! having on its periphery channel elements l8 whose section diminishes from the face l9 at which the fluid arrives towards the opposite face 20, these channels forming directional mouthpiece l4 and being formed to follow a helicoidal track on the. periphery of the core H, the pitch of the helix being variable, maximum near the face 19 and'minimum near the face 20, as shown in the drawing.
  • This core is connected by a spindle 2
  • An oper- 5 ating knob 24 enables the stem 2
  • a turbine wheel 25 mounted on an axle 26 rotating freely and which may comprise a braking device, not shown in the drawing.
  • the wheel 25 which is stopped, and which, owing to its inertia, only gradually starts to rotate, acts at first as a fixed distributor in such a way that the fluid threads passing out follow a direction indicated by the arrow ,1 (Fig. 35 3). Then, as the speed of rotation of the wheel increases, the direction of the fluid threads becomes less and less inclined to the axis, thus causing the formation of a conical sheet with decreasing apex angle.
  • a braking device may be arranged on the shaft 26 in accordance with the duration suitably calculated for the extinction of a burning zone, in such a way that the conical sheet which, at the commencement, has a maximum apex angle, only obtains its minimum apex angle at the end of ,a period in which the burning zone is completely extinguished.
  • the extinguishing device may, of course, use any desired extinguishing body, in any suitable physical state, liquid, gaseous, powdered or other wise, or a mixture of bodies in these various states.
  • the invention applies to fire extinguishing devices for all applications.
  • a nozzle for a fire extinguishing device comprising a cylindrical member, a member fitting within and movable relatively to said cylindrical member, said movable member having helical channels in its periphery, said channels diminishing in pitch from the inner towards the outer or discharge face of the member.
