ABSTRACT:
A temperature sensitive valve, and two embodiments of a sprinkler head operated by the valve. A sprinkler head core houses the temperature sensitive valve and has a supply conduit entering through the top surface of the head core. The first embodiment of the sprinkler head has a dispensing conduit extending through the side wall of the core. The dispensing conduit supplies fire fighting material to a ring with a plurality of radially spaced nozzles. A casing surrounds the core and supports the ring. The preferred embodiment of the sprinkler head has a plurality of fire fighting material dispensing ports that are radially and equidistantly arranged around the side wall of the core, thereby allowing fire fighting material to be dispensed in a 360.degree. pattern without the need for external conduits. The first embodiment of the core may also be used as a drip valve to prevent freeze damage in fire extinguishing or other fluid systems. In either embodiment, the valve of the present invention is within a cylindrical cavity inside the core of the sprinkler head. The cavity includes a large diameter top section and a small diameter bottom section, with a valve piston slidably mounted therein. The piston includes a main piston body, a top sealing disc that provides the valving action, and a bottom sealing disc that maintains alignment between the piston and the cavity. An ambient temperature sensor within the cavity, is operatively attached to the piston via an activating rod.
