Abstract:
1. A dry sprinkler comprising: a tubular outer structure defining a passageway extending along a longitudinal axis between an inlet and an outlet defining a K-factor of at least 5.6; a tubular inner assembly disposed within the tubular outer structure and movable along the longitudinal axis in the passageway between a first position and a second position, the tubular inner assembly including: a closure assembly supported by the at least one elongate member of the first yoke support end, the closure assembly occluding a flow of fluid in the passageway when the tubular inner assembly is proximate the first position; a projection coupled to the tubular outer structure between the inlet and the fluid tube to contact and translate the closure assembly to a side of the longitudinal axis when the inner tubular assembly moves from the first position towards the second position; a temperature responsive trigger assembly proximate the outlet of the tubular outer structure, the trigger assembly having a then rating of any one of about 135, 155, 200 and 286 degree Fahrenheit (° F.); and a fluid deflecting structure proximate the outlet of the tubular outer structure.
