Patent ID: 8419417

Claim:
A mold-tool system ( 100 ), comprising: a nozzle housing ( 102 ) having a melt passageway ( 103 ) extending from an input end ( 106 ) to an output end ( 108 ) being offset from the input end ( 106 ); and a valve stem ( 104 ) being: (i) slide movable along the melt passageway ( 103 ), and (ii) slide supported by the input end ( 106 ) and by the output end ( 108 ); and a nozzle tip ( 114 ) being received in the output end ( 108 ) of the nozzle housing ( 102 ), the nozzle tip ( 114 ) including: a flute structure ( 116 ) positioned proximate to an exit portal ( 118 ) of the nozzle tip ( 114 ), the flute structure ( 116 ) configured to slidably support the valve stem ( 104 ) while at the same time maintaining a flow area ( 400 ) surrounding the valve stem ( 104 ) along the entire length that the valve stem ( 104 ) is slidably supported by the flute structure ( 116 ) when the valve stem ( 104 ) is placed in the open position, the flow area ( 400 ) being equal to the flow area ( 300 ) defined by a cross sectional area of the exit portal ( 118 ) of the nozzle tip ( 114 ).
