Abstract
The present invention relates to an improved liquid dispenser machine for automatically dispensing small, medium or large cups of liquid and eliminates the oscillator required in prior art systems as well as provides feedback to prevent chattering and oscillatory operation of the liquid dispenser valve and also includes a predetermined time delay in the timing circuit which allows fast change of cups without starting the timer.
