Abstract:
A fire suppressing device automatically operable by exposure to fire temperatures of at least a predetermined degree, said device comprising:(a.) a canister housing of uniform cross section for containing a fire suppressing fluid under pressure, where said housing includes an axially slidable piston member having front and rear faces, and comparably shaped to said cross section, means for fluid sealing said piston member between said front and rear faces, energy storing means within said housing in contact with said piston member to effect its sliding movement; and, (b.) a canister end cap member closing said housing to define a cavity therewithin, where said end cap member includes an opening in communication with a nozzle mechanism, said nozzle mechanism comprising (i.) a conduit leading from said opening to a nozzle end, said nozzle end consisting of a cylindrical body portion of a first diameter, a smaller concentric portion having a nozzle face, and an annular shoulder separating said portions, (ii.) a cylindrical end cap, closed at one end and containing a central recess of a size to slidable engage said concentric portion, and, (iii.) a compression spring within said central recess to act against said nozzle face, where said cylindrical end cap, with said compression spring disposed therewithin, is secured to said cylindrical body portion by a solder which melts or softens at the at least said predetermined degree.
