Abstract
A dry pipe sprinkler assembly is provided including a sprinkler body having a thermally responsive trigger mounted thereto. A housing, including an inlet end and an outlet end is provided with the outlet end being connected to the sprinkler body. A seal member is disposed at the inlet end of the housing, and a load mechanism extends between the thermally responsive element and the seal member. The load mechanism may include a support portion, a passage tube portion, and an outlet orifice portion slidably received within the housing and movable within the housing upon activation of the thermally responsive trigger to allow the seal member to be dislodged from the inlet end of the housing to allow suppressant fluid to flow therethrough. The dry pipe sprinkler assembly allows the use of different outlet orifice members to provide dry pipe sprinkler assemblies having different K factors while utilizing common components for the remaining dry pipe sprinkler assembly.
