1. An automatic system for the selective distribution of liquid streams comprising:

  • a plurality of liquid delivery members, each having a liquid inlet and a liquid outlet and adapted to permit a liquid stream to flow therethrough;

    a valve associated with each liquid delivery member for varying the flow of said liquid stream therethrough comprising;

    a generally cylindrical body member comprising an inlet cavity, an outlet cavity, and a valve bore therebetween for providing fluid communication between said cavities;

    means for selectively controlling liquid flow through said valve bore comprising;

    a stopper member moveable along a central axis of said valve between a closed position, whereby said stopper substantially prevents said liquid from passing through said valve bore, and an open position, whereby a predetermined amount of liquid flows through said valve bore;

    means for biasing said stopper member toward said closed position; and

    means for moving said stopper to said open position to allow said predetermined amount of liquid to flow through said valve bore, said moving means including an electromagnetic controller capable of providing forces for displacing said stopper to any one of a number of positions each of which allow a different amount of liquid flow through said valve bore;

    wherein when said valve bore is open, said predetermined amount of liquid flows through said valve bore and exits through said outlet cavity;

    wherein the flow of said liquid through the liquid outlet of each of said delivery members is individually controllable by microprocessor means operating each of said valves.
