Abstract: A beverage tapper shut-off mechanism includes a double acting solenoid, a locking mechanism, a dispensing tube, and a housing. The locking mechanism has a cam actuator, an upper thrust arm, a lower thrust arm, and a tube crusher. The lower thrust arm is pivotally connected to the tube crusher and the upper thrust arm. The double acting solenoid is fastened to the housing, and the upper thrust arm is pivotally connected to the housing. The cam actuator is fastened to an actuation rod of the double acting solenoid. The cam actuator has an internal cam surface which controls the movement of the tube crusher. A modified dispensing tube has two sides which are molded to be substantially squeezed together. The double acting solenoid is operated by a control circuit. When a particular amount of beverage is needed, a button is pushed on the operational circuit. A pulse of current is sent to the double acting solenoid.
