ABSTRACT:
The present invention features an improved milking system that provides a precise, delineated transition between the pressure and vacuum phases of a pulsator mechanism. The system features a two-valve control that provides a sharp transition between the alternating air pressure and vacuum that are supplied to a teat cup. One valve of the pulsator mechanism controls the vacuum inlet; the other valve controls the atmospheric air inlet. The electronics actuating the valves alternates the air and vacuum supplied to the pulsator outlet, so that the vacuum and atmospheric air sources are never simultaneously connected to the pulsator outlet.
