ABSTRACT:
A sprinkler head includes a nozzle through which water is discharged to extinguish fire. The nozzle is normally held in a closed position. The nozzle is opened in the event of fire. A leaf spring is provided to hold the nozzle in its closed position and permit the nozzle to open. The leaf spring is deformed both in the axial direction of the sprinkler head and in a direction at right angles to the axial direction when an axial force is applied. Furthermore, the leaf spring and is resiliently returned to its original shape when the axial force is released.
