Abstract
A foam soap generator is provided for implementation with various types of foam soap delivery systems. The foam soap generator includes converging air and liquid soap passages at a mixing chamber, where a prefoam is generated for ultimate extrusion through a porous passage member. In one embodiment of the invention, the liquid soap is drawn into an entrainment zone by high velocity air passing through the air passageway and into the mixing chamber.
