ABSTRACT:
An apparatus for generating high expansion foam. The disclosed apparatus includes an elongated housing having an inlet and an outlet and a perforated member extending across its free passage area. A fan is positioned in the housing and drivingly rotated by impulse nozzles supplied with pressurized liquid foam solution. The nozzles are arranged tangentially to the rotational axis of the fan, in a plane normal to the axis. A deflector is positioned around the nozzles so as to direct jet spray of the liquid foam solution partially toward the central portion of the perforated member and partly toward the outer edge portion of the perforated member to provide a relatively uniform wetting of the perforated means. The deflector further provides means for permitting all the nozzles to be directed tangentially to the rotational axis in design and to be mounted at the greatest possible distance from the shaft to provide the largest moment arm in order to increase percentage of the power available in the water supply.
