Abstract
A firefighting nozzle has a low-turbulence liquid flow channel that is directed outwardly by a baffle. Surrounding the flow channel is an annular concentrate chamber. The concentrate chamber leads from a concentrate inlet to a concentrate entry port on a rearward wall opposed to the baffle. Liquid flowing past the baffle draws concentrate through the concentrate entry port into the flow. The concentrate and liquid subsequently mix to produce fire-fighting foam.
