Abstract: An FCB-making machine is provided with an adjustable faucet that is energized by a pressurized fluid such as carbon dioxide or air, which is controlled by a momentary-contact switch-actuated three-way solenoid valve. Dispensing is started by depressing the switch and terminated by releasing the switch (or automatically). By using this valve many conventional liquid drink dispensers, milkshake freezers and similar machines may be converted to the production of FCB's. A provision is made for performing faucet seal repairs without affecting the pressure or contents of the machine.
