Abstract
A sprinkler assembly that includes a deflector assembly that translates with respect to the sprinkler frame upon actuation of the sprinkler from an unactuated state. The sprinkler frame includes a support member having an annular member spaced from the outlet to limit or control the axial translation of the deflector assembly relative to the outlet. Moreover, the annular member includes a region to support a closure assembly and thermally responsive trigger assembly under a fluid static load. A cover plate assembly includes a flexible annular wall to allow the cover plate assembly to be pushed on and held about the annular member of the sprinkler frame.
