Claim:
A dual closure nozzle comprising: an outer sleeve having a central longitudinal bore for receiving in longitudinally movable interconnection an inner conduit, said outer sleeve having, in sequence, a receiving aperture for receiving said inner conduit, a fluid material flow chamber defined within said central bore and at least one discharge opening configured to allow passage of a fluid material out from said fluid material flow chamber of said outer sleeve, said outer sleeve further being longitudinally displaceable along said inner conduit from a first closed position through an intermediate open position to a second closed position; said inner conduit configured for positioning within said outer sleeve, said inner conduit having an inlet opening configured for the passage of fluid material from an external source into said inner conduit and at least one outlet opening configured for the passage of fluid material out from said inner conduit and into said fluid flow chamber of said outer sleeve; sealing means disposed between said outer sleeve and said inner conduit, said sealing means configured to prevent the passage of fluid material out from said outer sleeve and through said discharge opening when said outer sleeve is longitudinally displaced in said first closed position, to prevent the passage of fluid material out of said outer sleeve when said outer sleeve is longitudinally displaced in said second closed position, and to permit the passage of fluid material out from said outer sleeve and through said discharge opening when said outer sleeve is longitudinally disposed in said intermediate position; a spray directing device configured for connection with said outer sleeve, said spray directing device configured to direct liquid spray in a desired pattern in a desired direction; and a dampening device, said dampening device configured to dampen the flow of material through said device.
