1. On a frozen carbonated beverage freezer which has a dispensing head with an inlet for entry of a soft-frozen beverage and an outlet for discharge of said beverage into a drinking receptacle, and a first cylinder with a draw valve piston movable longitudinally in said cylinder to start and stop passage of said beverage from said inlet through a passageway to said outlet, the improvement comprising: a second cylinder attached to said first cylinder, and which has a piston rod; andat least a first member connecting the piston rod to the draw valve piston whereby longitudinal movement of said member resulting from longitudinal movement of the piston rod along a first axis is operable to move said draw valve piston longitudinally along a second axis to alternately start and stop passage of said beverage;wherein said first and second axes are offset and parallel. 2. The improvement of claim 1 and further comprising a bracket connecting said first cylinder to said second cylinder. 3. The improvement of claim 1 and wherein said first member is a shroud covering said first and second cylinders. 4. The improvement of claim 3 and further comprising a pin connecting the shroud to the draw valve piston in said first cylinder. 5. The improvement of claim 1 and further comprising: a flow rate adjuster connected to said draw valve piston and operable to limit the rate of passage of said beverage to said outlet. 6. On a frozen carbonated beverage freezer which has a dispensing head with an inlet for entry of a soft-frozen beverage and an outlet for discharge of said beverage into a drinking receptacle, and a first cylinder with a draw valve piston movable longitudinally in said cylinder to start and stop passage of said beverage from said inlet through a passageway to said outlet, the improvement comprising: a second cylinder attached to said first cylinder, and which has a piston rod;at least a first member connecting the piston rod to the draw valve piston whereby longitudinal movement of said member is operable to move said draw valve piston to alternately start and stop passage of said beverage;a second piston in said second cylinder; andports on said second cylinder to opposite ends of said second piston for selectively admitting into said second cylinder on opposite ends of said second piston, pressurized fluid, to selectively start and stop passage of said beverage from said inlet to said outlet. 7. The improvement of claim 6 and wherein: said freezer has a supply of carbon dioxide; andfluid conduits are coupled to said ports and to said supply. 8. The improvement of claim 7 and further comprising: a fluid control valve which has an inlet port coupled through one of said conduits to said supply; and wherein:said control valve has two outlet ports, and one of said outlet ports is coupled through one of said conduits to one of said ports on said second cylinder, and the other of said outlet ports is coupled through another of said conduits to the other of said ports on said second cylinder;said control valve can be shifted from one condition applying pressurized carbon dioxide to one of said ports in said second cylinder, to another condition applying pressurized carbon dioxide to the other of said ports in said second cylinder whereby said control valve is operable to selectively cause said member to move said flow valve in one direction or an opposite direction. 9. The improvement of claim 8 and further comprising: a solenoid coupled to said fluid control valve; anda user operable switch on said freezer and coupled to said solenoid and operable responsive to actuation by a user to cause said second cylinder to move said draw valve piston to permit passage of said beverage; anda responder coupled to said fluid control valve to cause said second cylinder to return said draw valve piston to stop said passage of said beverage. 10. The improvement of claim 9 and wherein: said responder is responsive to the receptacle state of fill to return said draw valve piston to stop said passage. 11. The improvement of claim 9 and wherein: said responder is responsive to a sensor signal to stop said passage. 12. On a frozen carbonated beverage freezer which has a dispensing head with an inlet for entry of a soft-frozen beverage, and an outlet for discharge of said beverage into a drinking receptacle, and a first passageway for said beverage from said inlet to said outlet, and a first cylinder with a draw valve piston movable longitudinally in said cylinder to start and stop passage of said beverage from said inlet to said outlet, the improvement comprising: an apparatus coupled to said head for admission of at least one flavoring liquid into said passageway for blending into a beverage base flowing from said inlet toward said outlet when said draw valve piston is in position to start flow of said beverage base from said inlet toward said outlet;wherein said apparatus includes two tubes extending into said passageway to deliver the at least one flavoring liquid into said passageway, wherein each of said tubes defines an open end in communication with said passageway and at least one slot in communication with said passageway. 13. The improvement of claim 12 and wherein said tubes are vertically. 14. The improvement of claim 12 and wherein said tubes are spaced from each other longitudinally in said passageway and offset toward opposite sides of a longitudinal axis of said passageway. 15. The improvement of claim 12 and further comprising: a flavoring liquid storage and delivery device coupled to said apparatus to deliver to said apparatus, upon request, flavored liquid of flavor specified in the said request. 16. On a frozen carbonated beverage freezer which has a dispensing head with an inlet for entry of a soft-frozen beverage, and an outlet for discharge of said beverage into a drinking receptacle, and a first passageway for said beverage from said inlet to said outlet, and a first cylinder with a draw valve piston movable longitudinally in said cylinder to start and stop passage of said beverage from said inlet to said outlet, the improvement comprising: modification of said head, and an apparatus coupled to said head for admission of a flavoring liquid into said passageway for blending into a beverage base flowing from said inlet toward said outlet when said draw valve piston is in position to start flow of said beverage base from said inlet toward said outlet;wherein said apparatus further comprises:a source of pressurized CO2;a first valve coupled to said source and operable to cause said draw valve to open and close;a second valve coupled to said source to said second passageway and operable to cause said CO2 to purge said flavored liquid from said second passageway. 17. On a frozen carbonated beverage freezer which has a dispensing head with an inlet for entry of a soft-frozen beverage, and an outlet for discharge of said beverage into a drinking receptacle, and a first passageway for said beverage from said inlet to said outlet, and a first cylinder with a draw valve piston movable longitudinally in said cylinder to start and stop passage of said beverage from said inlet to said outlet, the improvement comprising: modification of said head, and an apparatus coupled to said head for admission of a flavoring liquid into said passageway for blending into a beverage base flowing from said inlet toward said outlet when said draw valve piston is in position to start flow of said beverage base from said inlet toward said outlet;wherein said head further comprises: a first port in the exterior of said head; anda second passageway in said head and communicating with said first port and said first passageway;wherein said apparatus further comprises:a tube in said second passageway from said first port into said first passageway for injection of said flavoring liquid into said beverage base, wherein said tube has outlets in said first passageway for blending said flavoring liquid into said beverage base across the cross sectional area of said first passageway;a third passageway in said head and communicating with said first port and said first passageway;a second tube in said third passageway and which has outlets in said first passageway, and wherein: said outlets are spaced from each other longitudinally in said first passageway and offset toward opposite sides of a longitudinal axis of said first passageway; andsaid outlets comprise slots in sides of said tubes. 18. The improvement of claim 17 and wherein: said tubes are open ended in said first passageway, and said slots extend from the open ends of said tubes toward a surface defining the inside wall of said first passageway. 19. The improvement of claim 12 and wherein said slots extend from the open ends of said tubes toward a surface defining the inside wall of said passageway.
