Abstract: A fire protection sprinkler including a frame body having an inlet, an outlet, defining an internal passageway extending between the inlet and the outlet along a sprinkler axis. A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface. The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.

Abstract: A fire protection sprinkler that includes a body defining an internal passageway extending along a sprinkler axis between an inlet end and an outlet end to define a passageway length and a nominal K-factor greater than 16. A deflector is supported and spaced from the outlet end by a pair of support arms. The sprinkler includes means for allowing a flow of water from the outlet end of the body. The means includes a closure assembly having a body defining a blind bore and a thermally responsive glass bulb. The glass bulb has a first end disposed within the blind bore defining a first seat diameter and a second end defining a second seat diameter. The glass bulb has a bulb length that is greater than the length of the internal passageway and a maximum wall thickness less than the difference between the bulb length and the passageway length.
