Abstract
An improved valve actuator is provided to operate a liquid dispenser valve of the type used in a soft drink dispenser station or the like. The dispenser station includes a pressurized supply of carbonated water for regulated delivery through a water dispense conduit to a drinking cup or the like for mixture with a selected flavor syrup delivered to the cup from a syrup-containing bottle having the dispenser valve at the bottle neck for controlling syrup outflow. The valve actuator is mechanically connected to the dispenser valve and responds to pressure along the water dispense conduit at a position upstream of a flow restrictor to open the dispenser valve each time carbonated water is delivered through the conduit to the drinking cup. At the conclusion of water delivery, the valve actuator responds to decreased pressure along the water dispense conduit to return the dispenser valve to a closed position.
