<p>In an injection molding machine, a distributor duct apparatus (10) for delivering a selected fluid to two or more separate, fluid driven cylinders (20) each of which is mounted on a heated manifold (30) and is interconnected to a valve pin (60) for effecting reciprocal movement of the valve pin (60) wherein the reciprocal movement of the valve pin (60) controls the flow of molten plastic being delivered through a nozzle which delivers molten plastic to a gate of a mold, the distributor duct apparatus (10) comprising: a distributor housing (10) mounted on an outside surface (25) of each of the cylinders (20), each of the cylinders (20) having a piston (80) slidably mounted within the bore (90) of an enclosed cylinder housing (20) for reciprocal fluid driven movement of the piston (80) within the bore (90) of the cylinder housing; the distributor housing (10) having at least two fluid flow channels (200,210), one channel (200) sealably communicating with a first fluid input/output port (203,204) to the bore (202) of each cylinder housing (20) and another channel (210) sealably communicating with a second fluid input/output port (213,214) to the bore (212) of each cylinder housing (20). <IMAGE></p> |
