A beverage dispensing apparatus includes a beverage dispensing head wherein a rigid plate is disposed over a mixing fluid valve stem and a plurality of base fluid valve stems. The plate has an opening located over each base fluid valve stem for receiving the associated base fluid valve stem therethrough. The plate has a rigid surface disposed over the mixing fluid valve stem. A mixing fluid button contacts the rigid surface of the plate so that, when the mixing fluid button is depressed, only the mixing fluid is dispensed. A first base fluid button covers the opening in the plate disposed over its associated base fluid valve stem. The first base fluid button also contacts the plate so that, when the button is depressed, the button depresses both the base fluid valve stem and the plate. The plate, in turn, depresses the mixing fluid valve stem. A second base fluid button includes a projection which extends through the opening in the plate without contacting the plate for depressing only its associated base fluid valve stem.

In a beverage dispensing head of the type for use with pressurized sources of base and mixing fluids coupled to the head by a plurality of fluid conduits, the head including a plurality of fluid passageways connecting the fluid conduits to a discharge nozzle with associated base and mixing fluid valves controlling the flow of fluid along the passageways, the base and mixing fluid valves including base and mixing fluid valve stems which move between valve closed and valve open positions for selectively closing and opening the base and mixing fluid valves, the base and mixing fluid valve stems being biased in the valve closed position, the improvement comprising: a plate disposed over a base fluid valve stem and a mixing fluid valve stem, the plate having an opening located over the base fluid valve stem capable of receiving the base fluid valve stem therethrough, and the plate having a rigid surface disposed over the mixing fluid valve stem; and first plate moving means for moving the plate toward the base and mixing fluid valve stems so that the rigid surface of the plate causes the mixing fluid valve stem to be in the valve open position, and so that the base fluid valve stem passes through the opening in the plate for maintaining the base fluid valve stem in the valve closed position; and second plate moving means for moving the plate toward the base and mixing fluid valve stems, the second plate moving means including base fluid valve stem impeding means for impeding the passage of the base fluid valve stem through the opening in the plate, so that the rigid surface of the plate causes the mixing fluid valve stem to be in the valve open position, and so that the base fluid valve stem impeding means impedes the passage of the base fluid valve stem through the opening in the plate and causes the base fluid valve stem to be in the valve open position.
