ABSTRACT:
In the particular embodiments of the quick response sprinkler described in the specification, a sprinkler housing is sealed with a valve plug supported on a deflector which is movable between a closed position and an open position. A thermally responsive element supported from a first lever which engages the valve plug has a plunger supporting a second lever and a third lever maintains the spacing between the first and second levers. When the thermally responsive element is actuated by elevated temperature, the plunger moves away from the levers, permitting the levers to separate and releasing the entire valve-retaining mechanism from the sprinkler housing.
