Definitions

  • the invention relates to a spray nozzle according to the preamble of claim 1.
  • Such a spray nozzle is known from US Pat. No. 3,812,915.
  • This known spray nozzle has a thermal trigger element on that when a certain temperature is reached melts.
  • Parallel to this melting thermal Trigger element is a spring, which in the event of a safety i.e. when the thermal release element has melted is pushing the lever arm away from the valve body so that the nozzle opening can be released. So it's on the side two elements, the thermal release element and the Feather present. This makes assembly difficult and the spray nozzle is complex overall.
  • the invention is based on the object of a spray nozzle to create the type mentioned, in which the trigger element is not only kept safe, but at with a simple construction, a simple assembly of the trigger element is possible.
  • the thermal release element is a conventional glass barrel.
  • the travel of the lever arm exploited to the thermal trigger element, for example the glass kettle to position in place.
  • the lever arm not only supports the thermal release element but it is also a spring element.
  • the device is designed as in claim 2 specified, then it is ensured that the overlapping Holders with lever arm do not move laterally can. So the lever arm is held once by that he form-fit the parallel sides of the nozzle head hook-shaped surrounds and the other in the incision lies in the end face of the nozzle body.
  • the groove according to claim 3 serves the safe and immovable Arrangement of the bearing lever, the protruding lever arm lies opposite and between the and the lever arm thermal trigger element is arranged.
  • the spray nozzle shown in the drawing consists of a Base body 1, which is installed as it is in the Drawing is shown, i.e. the one with the container for the Extinguishing liquid connected bore 16 is at the top.
  • a conical and circular Valve seat 7 is provided, the valve body 3 in the form picks up a bullet.
  • a swirl insert 2 is positioned in front of the valve seat .
  • the valve body 3 is held by a holder 5 which made of spring steel as it is from the drawing results. It has two lever arms 13 and 14. The one lever arm 14 is hooked into the nozzle body at 15. It stops the valve body 3 on the seat. The other lever arm 13 resilient with respect to the lever arm 14 and protrudes laterally. It has an opening 11 for receiving the thermal release element on.
  • the other end of the thermal release element is in an opening 12 in a bearing lever 4, which is also a Stamped part is and fastened in a groove 9 in the base body 1 is.
  • the bearing lever 4 has two screens 10 for protection the tip of the thermal release element 6, which in this Trap is a glass vial, on.
  • thermal release element 6 with its longitudinal axis substantially parallel to the longitudinal axis of the base body 1, but lies next to this. This creates a low overall height, and the individual Components are simple and inexpensive to manufacture.
  • asymmetrical storage together with the spring action of the holder, i.e. the preload ensures that the parts that are triggered when a In the event of a fire, must be safely removed become.
