ABSTRACT:
A volumetrically variable soap chamber partially collapses in response to an initial increased pressure state imposed by initiation of water flow and a predetermined quantity of liquid soap will be dispensed. The soap chamber is replenished from a source of liquid soap in response to a reduced pressure state in the soap chamber imposed by the cessation of water flow.
