As the piston moves to the second position, the piston allows the plug to change from the partially open position to the fully open position.
  • the known fire extinguishing systems are often used in buildings in which the room conditions change over time, for example, because in-premises facilities or storage items be stored, modified or removed. Furthermore, it may happen that parts of the fire extinguishing system are updated and changed, for example, including the extinguishing agents used. In such cases, an adaptation of the extinguishing fluid nozzles is necessary, which is associated with the known systems with high temporal and structural complexity. This has proven to be a disadvantage. Another disadvantage that is found in the prior art, is that after the introduction of an aperture in a nozzle, whether by installation of a diaphragm ring, or by introducing one or more aperture holes, subsequently no longer readily detectable, which inner diameter has the aperture.
