Abstract: A fire extinguishing apparatus (A) actuated either manually or automatically for dispensing a stream of pressurized fire extinguishing fluid (F) in a preferred pattern. The apparatus includes a storage tank (10) for the extinguishing medium which is operably connected with a discharge nozzle assembly (14). A conventional flexible dip tube (30) is secured within the tank in a novel manner to insure complete discharge of the tank contents which is preferably selected from various Halon agents. The discharge nozzle assembly (14) is sealed by a closure member (40) which is held in the discharge blocking position by a temperature sensitive bulb (38) and a leaf spring (36). Operation of the temperature sensitive bulb (38) enables automatic extinguisher operation which manual actuation removes the leaf spring. Either actuation releases the closure member to effect operation. The extinguishing fluid is released through slots (34d) on the sides of the nozzle (34).
