ABSTRACT:
A fluid dispensing nozzle has a first venturi created between a seat ring and a movable, resiliently biased poppet valve. The resistance of the movable poppet valve is decreased as the flow rate increases by a second venturi effect, which reduces the pressure in a chamber formed within the movable poppet valve.
