Abstract
A nozzle shut-off valve for the plastication system of an injection molding machine. The valve includes a cylindrical body member that has axially spaced inlet and outlet passageways. Inclined passageways that extend from the inlet and outlet passageways to the outer surface of the body member to terminate in spaced openings on the periphery of the inner body member. A tubular outer member is provided with at least one recess or depression on its inner surface, the recess having a length sufficient to provide communication between a pair of the spaced peripheral openings in the inner body member when the recess is positioned in overlying relationship with the respective openings. Rotation or translation of the tubular outer member relative to the inner body member shifts the recess out of registration with the respective peripheral openings, to thereby prevent flow of material through the valve. Shifting of the outer member is accomplished by means of a pneumatic cylinder that is carried by the inner body member to shift the tubular outer member relative to the cylindrical body member.
