Abstract
A fire-fighting system, which includes a nozzle housing having a turbulence chamber with a nozzle aperture communicating with the turbulence chamber and a temperature responsive compressive element which gives way at a specified temperature, and which compressive element and a sealing unit for the nozzle are held in place against the nozzle by a spring under compression which is released when the compression element gives way at a specified temperature.
Claims18
An atomizer for generating a water mist in fire-fighting systems, comprising a housing, a turbulence chamber mounted in the housing, and a nozzle aperture communicating with said turbulence chamber, and including:
- a) a sealing unit (18, 20) externally resting against the housing (1) and tightly sealing the said nozzle aperture (5);
- b) a compressive element (25) pressing the sealing unit (18, 20) against said nozzle aperture and giving way at a specified initiation temperature;
- c) said compressive element having one end resting away from said sealing unit (18, 20) against a part (33) connected with said housing (1);
- d) said part including releasable spring means when connected to said housing (1) being compressed for connection to said housing (1);
- and
- e) whereby when said compressive element gives way at a specified temperature, said sealing unit will be unseated from said nozzle aperture to permit said atomizer to generate water mist.

- c) said support including a fork having two legs (31, 32);
- d) said housing including projections for locking said legs (31, 32) in a first pre-stressed position;
- and
- e) said legs including protrusions gripping said compressive element (25) for securing said legs against being spread apart prior to activation of said atomizer.
