Abstract
A foam expansion tube for a fire fighting nozzle includes a tubular body with a longitudinal axis and a passageway extending there through along the longitudinal axis for directing a foam and water mixture from a fire fighting nozzle. The passageway has a larger diameter than the outlet of the nozzle to provide an expansion tube for the foam/water mixture. The tubular body further includes an inlet end and an outlet end, with the inlet end having an inlet adapted for mounting to the outlet of the fire fighting nozzle for receiving the foam/water mixture into the passageway and having at least one opening to allow air to be drawn into the passageway for mixing with the foam/water mixture flowing through the passageway. The tube further includes a structure that extends into the passageway wherein the structure separates the foam/water mixture to further enhance the expansion of the foam and water mixture.
