1. A self-cleaning cofluid dispensatory valve adapted to maintain separation of a first fluid from a second fluid prior to effluence, which comprises:

  • a housing having an upper open end first fluid transit chamber separated from a lower second fluid transit chamber;

    a resilient annular sealing barrier disposed within said housing to maintain sealing separation of said chambers;

    a unifier means affixed on said first fluid transit chamber to retain said valve in a definable unit;

    a resilient annular gasket adapted to provide sealing closure at said open end;

    a resiliently mounted dispensatory actuator means that includes an outwardly projecting, depressible, stem member that maintains slidable sealing engagement with said gasket and cooperative valvular engagement with said barrier;

    an annular valve seat means fitted loosely around said stem, and positioned engagingly between said gasket and said barrier;

    said valve seat being normally seated between said gasket and said barrier, and unseated by axial movement along said stem;

    said stem further maintaining cooperative sealing engagement with central portions of said barrier to urge said seating and unseating and maintain sealing separation of said chambers;

    said stem also including a discharge passageway that is provided with at least one fluid port and at least one second fluid port;

    said ports each situated to allow first fluid discharge flow through said stem passageway when said actuator is in an intermediate operating position, whereas, said valve seat means is unseated;

    said first and second fluid ports further being situated to be within respective first and second fluid transit chambers to allow concurrent flow of first and second fluids through said stem passageway when said actuator is operated to its lowermost position, for cofluid dispensing;

    said valvular engagement being adapted to allow fluid flow communication between said second fluid port and said second fluid transit chamber when said actuator is operated for cofluid dispensing.
