1.2 Water Flow (cont.)
Figure 7
The position of the piston inside the sleeve is determined by the upward pressure of the liquid against the
base of the piston and the downward pressure of the spring inside the piston (not shown here). The pressure
of the spring is regulated by the adjusting screw.
If the pressure of the liquid increases, the flow rate through the knife–edged orifice will increase. The piston
is moved upward closing off more of the outlet orifices. The sameflow rate is thereby maintained.

1.3 Adjusting Flow Rates

Flow rates of the water and syrup are adjusted based on the desired ratio. For example: if the desired ratio is
5:1, then the flow rate of the water is 5 times that of the syrup. If the desired finished drink total flow rate is
3.0 ounces per second, then the water flow rate is 2.5 oz./sec and the syrup flow rate is 0.5 oz./sec. (The
water at 2.5 oz./sec is five times the 0.5 oz./sec syrup flow rate.)
Note: Always adjust water within its range.
