value, the trigger mechanism, which is normally a fusible link, separates permitting the pins to move in an outward direction under the pressure of the water. With the separation of the fusible link, the pressure in the water supply line pushes the fluid seal away from the outlet opening and the deflector to its outward position thereby enabling the water to travel through the sprinkler body and to be dispersed by the deflector.
In side wall mounted sprinklers, however, the ejection of the trigger assembly may slow the release of the deflector from within the housing of the flush sprinkler assembly. Additionally, the orientation of the assembly causes the pressurized water to disperse in a horizontal direction. While attempts have been made to redirect the flow of the waterthe sprinkler body, and aligns the deflector with the path of the water when it is discharged through the outlet opening. The arms are often joined at their distal ends by a boss, which is used to mount the deflector to the arms. Pendent sprinklers and upright sprinklers typically include deflectors with a solid central portion and a plurality of tines that extend radially outwardly from the central portion for dispersing the fluid as it flows across the solid central portion, which is mounted to the boss and typically aligned with the discharge opening of the base. Sidewall sprinklers typically include a deflector, also with a solid central portion with tines extending from the central portion and a blade that is positioned above the central portion to direct
