Abstract
A stove-hood fire extinguisher system includes a reservoir for fire extinguishing agent, and a distributor arm which in turn includes a fluid tube and an actuator tube. An extinguisher valve connects the reservoir to the fluid tube, and includes a valve stem extending into the actuator tube. A fuse mechanism on the distributor arm includes a fuse element, a movable trigger extending from the fuse element into the actuator tube, and a tightener to press the fuse element against the trigger. An actuator mechanism in the actuator tube includes an actuator rod with a detent block on one end for engagement with the trigger and a ramp on the other end for engagement with the valve stem, and a compression spring urging the ramp toward the valve stem. The trigger extending into the detent groove holds the actuator rod in a retracted position. Rupture of the fuse element releases the trigger from the detent groove, and the spring drives the actuator rod and ramp against the valve stem to open the extinguisher valve.
