ABSTRACT:
A foam generating apparatus can be attached to a water bearing hose and comprises an eductor nozzle to receive water and foam concentrate, and a foam generating nozzle to discharge a foam/water mixture therethrough. A foam concentrate conduit delivers concentrate to a manifold extending peripherally around a suction port of the eductor nozzle, and foam concentrate is drawn into the eductor nozzle to mix with water and to be discharged as a foam/water mixture to the foam generating nozzle. The nozzle has an agitator jet orifice for agitating the mixture, and an air entrainment opening to admit air into the agitated mixture. The agitator jet orifice has inlet and outlet jet openings interconnected in series, the outlet jet opening being larger than the inlet jet opening to provide a diverging passage with at least one step between the inlet and outlet jet openings to agitate the flow. The step has an abrupt step edge to enhance agitation and is relatively long when compared with cross-sectional area of the inlet jet opening. The inlet jet and outlet jet openings are non-circular, and preferably elongated slits to provide a long length of step.
