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