ABSTRACT The discharge bore of a liquid ice cream reservoir supports a metering device extending into it. Liquid mix flows from the reservoir through an orifice in the metering device into an inner bore. Suction created by the liquid flow draws air into the inner bore through an air metering orifice where it mixes with the liquid, the mixture then flowing by gravity to the freezer barrel. An inner valve body within the metering device contains a plurality of metering orifices of incrementally increasing sizes which can be selectively aligned with a discharge orifice to control the flow rate of the liquid. Indicia on the valve body provide a visual indication of the orifice selected.
