FIRE PROTECTION SPRINKLER TRIGGER ASSEMBLY

摘要

A sprinkler assembly including a sprinkler frame having a proximal portion, a distal portion and an internal surface defining an internal fluid passageway having an inlet and an outlet extending axially to define a central sprinkler axis of the frame. The distal portion includes a plurality of surfaces to define a pair of chambers disposed about the passageway. The sprinkler assembly includes a seal assembly and a lever assembly having a first configuration to support the seal assembly and a second configuration to release the seal assembly. The lever assembly includes a pair of lever members in which each lever member has a first end. In the first configuration, the first end forms a frictional engagement within a chamber to support the seal assembly in an unactuated state of the sprinkler frame.
