ABSTRACT:
A spray nozzle for combating fires that includes a housing having a flat end face and a contoured chamber passing upwardly through the end face. A plate is supported adjacent to the end face to provide a circular spray opening therebetween. A fire extinguishing fluid is pumped through a rigid pipe from a high pressure supply into the chamber where the fluid is expanded into a vortex before being projected through the spray opening in a 360.degree. pattern. The pipe enables the nozzle to be inserted into the fire region by a firefighter situated at a remote and relatively safer location.
