ABSTRACT:
An aspirating foamer having a water inlet path to admit water into the nozzle assembly, two diametrically opposed foaming material inlet paths perpendicular to the water inlet path, and a conical conduit wherein the pressurized water and foaming materials mix and are allowed to expand; and an air inlet valve at the exiting end of the conical conduit for admitting air; and an exiting path for the foam. In one foamer (2) the conical conduit has an outwardly tapered angle of approximately 5 degrees (from centerline) initially with an immediate increase to an outwardly tapered angle of about 7 degrees in the second half of the conical conduit. In another embodiment foamer (102) according to the invention the conical conduit has an initial taper of 21/2 degrees followed by a 15 degree diffusion angle and then a 7 degree angle.
