Abstract
An apparatus for making and dispensing foam has a housing forming a generally closed foaming chamber, a liquid pump for drawing liquid from a supply and spraying the liquid into the foaming chamber, and an air pump for forcing air into the foaming chamber. A conduit forms a continuously open passage having an inner end opening into the foaming chamber and an outer end open to outside. A foam generator in the foaming chamber mixes the spray and air therein to generate foam and expand the foam to flow through the conduit out the outer end thereof. The liquid pump includes a small-diameter liquid chamber and a small-diameter liquid piston displaceable therein and the air pump includes a large-diameter air chamber and a large-diameter air piston displaceable therein and coupled directly to the liquid piston.
