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.
