ABSTRACT:
A firefighting nozzle for discharging a foam and water mixture. The firefighting nozzle has an inner nozzle concentrically positioned within an outer barrel. A baffle in the shape of an inverted cone is position at the outlet of the inner nozzle. The axial position of the baffle determines the flow rate of the foaming agent. The inner nozzle itself is also axially movable within the bore of the outer barrel, the axial position of the inner nozzle determining the flow rate of water between the outer barrel and the inner nozzle.
