ABSTRACT:
An automatic fire extinguishing discharge valve capable of attachment to a fire extinguisher thereby enabling automatic discharge of extinguishing medium upon sufficient impact or temperature rise. The automatic feature is controlled by maintaining a temperature sensitive trigger mechanism of a predesigned mass in opposition to a spring force attempting to drive a puncturing mechanism into the fire extinguisher. So long as the trigger mechanism remains in place the fire extinguisher will remain at the ready position and will not discharge the suppressant.
