ABSTRACT:
A foam generating nozzle is made either as an attachment to an existing liquid spray nozzle unit or as a pre-manufactured assembly and includes a foam-generating section having a pressure-reducing passageway including a preferably sharply outwardly tapering portion leading to a venturi-forming throat portion, and adapted to receive the liquid stream issuing from an inlet orifice. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. Optimum foaming action is achieved by adjusting the point of the pressure-reducing passageway struck by the stream which is most advantageously achieved by adjusting the angle of the stream issuing from the orifice so the widest portion thereof strikes the end section of the tapering portion of the passageway.
