Definitions

the present invention relates to a sprinkler for a fire extinguishing system.
FR 3 002 151 A1 shows a prior art sprinkler.
the sprinkler comprises a sprinkler body in which an extinguishing agent channel is formed. In the sprinkler's standby state, the outlet of the extinguishing agent channel is closed with a plug.
the sprinkler comprises an ejection element to direct the ejection movement of the plug.
the extinguishing agent channel is released by removing the plug, allowing extinguishing agent to escape and fight the fire.
a spray deflector is typically arranged in front of the outlet opening of the extinguishing agent channel to deflect and distribute the escaping extinguishing agent in an appropriate manner.
the plug For reliable extinguishing, the plug must be removed from the outlet opening of the extinguishing agent channel in such a way that the spread of the extinguishing agent is not impeded by the plug.
the plug In the standby state, the plug can be held in position by a trigger element against any overpressure in the extinguishing agent channel, so that the plug seals the extinguishing agent channel.
the trigger element releases the plug, so that the plug is forced out of the extinguishing agent channel under the influence of the overpressure in the extinguishing agent channel.
the plug should be completely removed from the sprinkler area after the sprinkler has been activated, as otherwise the extinguishing process could be impaired. If, for example, the plug were to become lodged between the extinguishing agent channel and the spray deflector, the escaping Extinguishing agent would hit the plug instead of the spray disc and the extinguishing agent would be diverted uncontrollably.
an ejection element can be arranged between the plug and the sprinkler body to direct the plug's movement.
Sprinklers are known in which the ejection element directs the plug along an arcuate path.
the arcuate path results from the fact that the counterbearing of the sprinkler body defines a pivot axis around which the ejection element pivots during the plug's arcuate movement.
the pivot axis is aligned parallel to the plane of the plug, so that the arcuate movement of the plug essentially takes place in a plane in which the extinguishing agent channel also extends.
the ejection element engages with the plug and with a counterbearing formed on the sprinkler body to direct the ejection movement of the plug through a pivoting action.
the counterbearing defines a pivot axis that forms an angle with the plane of the plug.
Fig. 3 shows a schematic top view of the sprinkler according to the invention from Fig. 1 and 2
the sprinkler body 13 is provided on both sides with a receptacle 32, each open to one side, for a clamping bracket 38.
the clamping bracket 38 can be tightened with a nut 35.
a retaining projection 33 is formed on the sprinkler body 13, which holds the nut 35 in its position when mounted and prevents the clamping bracket 38 from slipping sideways out of the receptacle 32.
Fig. 5 shows a perspective view of a sprinkler according to the invention mounted on a pipe 37.
the interior of the pipe 37 is filled with extinguishing agent and connected to the bore 14 of the sprinkler body 13 of the sprinkler.
