ABSTRACT:
A dispenser for liquids having an insulated cool chamber to receive a liquid container with a flexible tube for flow of liquid, a heat exchanger or pump in the chamber to pump liquid along the tube, a shut-off valve in the chamber below the pump with an opening for the tube to pass to a dispensing point outside the chamber, a motor and shaft for driving the pump, and gears connected between the motor shaft and the pump, a revolution counter coupled to the motor shaft, and connected to a counter logic circuit to count each revolution of the motor shaft, and manual controls mounted on the chamber and connected to the shut-off valve and to the motor, and to the counter logic circuit so that the shut-off valve opens within the chamber and the motor is started thereby driving the pump within the chamber, and automatically stopping the motor shaft when the predetermined count is reached, thereby maximizing the accuracy of the volume of liquid pumped by the pump.
