Abstract

A foam-applying nozzle assembly (N) having adjustable flow rates for applying a foam made up from a supply of a foam-forming liquid composition (F) and a flowing liquid stream (W) includes an inner barrel (I) having an axial bore (10) for communicating the liquid stream (W) from a hose. Eductor means (E) with the inner barrel (I) extracts the foam-forming liquid composition (F) from the supply of the foam-forming composition. The eductor means (E) inducts the extracted foam-forming liquid composition (F) into a first portion (W1) of the liquid stream (W) flowing through the eductor means (E). The eductor (E) has a discharge opening (22o) in proximity to the outlet (10m) of the inner barrel (I) for mixing the foam-forming composition (F) with the liquid stream (W) from the inner barrel (I) in proximity to the discharge of the liquid stream, whereby a foam is created. A deflection plate (32) is mounted inwardly and spaced apart of a mixing plate (12) which is mounted substantially perpendicular to the longitudinal axis (A) of the axial bore of the inner barrel (I). The deflection plate (32 ) is formed having slanting ducts (32a) to communicate a second stream portion (W2) to a mixing chamber 13. Ducts (32a) slant at an angle whereby second stream portion (W2) reflects from the mixing plate (12) to a slanted reflection edge (58) of the inner barrel (I).
