A foam soap generator (24) is provided for implementation with various types of foam soap delivery systems. The foam soap generator (24) includes converging air and liquid soap passages (46,48) at a mixing chamber (62), where a prefoam is generated for ultimate extrusion through a porous passage member (64). In one embodiment of the invention, the soap and air are delivered through coaxial tubes, with the soap being introduced axially into the mixing chamber (62) and the air being introduced radially angularly. In another embodiment, the liquid soap is drawn into an entrainment zone (80) by high velocity air passing through the air passageway and into the mixing chamber. |
