<p>The invention relates to an improved diffuser for projecting expandable polyurethane in an aerosol container, consisting of an accessory which, provided it is coupled to a pistol and to a hose carrying compressed air from a compressor, is used to project, from a distance, expandable polyurethane contained in an aerosol container. The diffuser has a body comprising a threaded section, a nut, a coupling joint, a sleeve and a projection nozzle with a foam outlet and a rounded groove. The diffuser can either be produced by injection as a single part, or as independent parts to be subsequently assembled, or as an assembly of all of the parts except the projection nozzle which is interchangeable according to different diameters of the foam outlet.</p> |
