Abstract
A dispenser and method for dispensing a liquid. The dispenser includes a barrel with an interior chamber for holding the liquid, a discharge outlet communicating with the interior chamber for discharging the liquid, and an air space for receiving pressurized air for forcing the liquid from the interior chamber through the discharge outlet. An air supply solenoid valve and an air exhaust solenoid valve are each operatively coupled with the barrel. The air supply solenoid valve controls the flow of pressurized air to the air space, and the air exhaust solenoid valve controls the flow of air from the air space to atmosphere. A control selectively activates the air supply solenoid valve and the air exhaust solenoid valve to respectively supply air to the air space and exhaust air from the air space in order to dispense desired amounts of the liquid from the discharge outlet.
