Abstract: A flavor mixing and dispensing device for a frozen confection machine including an upright valve cylinder having a discharge outlet at its lower end and a frozen confection inlet port and a plurality of flavoring inlet ports spaced above its lower end. A rotary mixer is provided in the lower portion of the cylinder and a valve piston is slidable in the valve cylinder. The valve piston is formed with a downwardly opening cavity means for receiving the rotary mixer, and the rotary mixer and valve piston are constructed and arranged so that the mixer telescopes into the cavity means in the valve piston when the piston is moved to its lower position, and the mixer and valve piston substantially fill the mixing chamber in the lower portion of the valve cylinder to displace substantially all material from the valve cylinder at the end of a dispensing operation.
