ABSTRACT:
An apparatus for producing and dispensing an aerated frozen confection in which a pump is mounted in the liquid ingredients reservoir of the apparatus and operates to pump a mixture of air and liquid ingredients, in selected proportions, to the freezer compartment of the apparatus. The pump itself is responsive to pressure within the freezer compartment to regulate the volume of mixture supplied to the freezer compartment by the pump for enabling automatic replenishment of the aerated mix in the freezer compartment. The pump includes a plunger projecting into the freezer compartment and driven by a cam which rotates with an agitator in the freezer compartment to move the plunger against the bias of a spring in the pump so as to reciprocate the plunger until the pressure within the compartment is great enough to move the plunger away from the cam, against the bias of the spring, thereby discontinuing the supply of mix to the freezer compartment.
