Abstract
A molten plastic delivery system is disclosed having a nozzle defining a nozzle channel with a downstream nozzle channel opening. A valve pin is reciprocable within the nozzle channel between a closed position and an open position. The system includes a bell crank having first and second arms that are connected at and rotatable about a pivot. The first arm is coupled to the valve pin and the second arm is coupled to a push-pull cable such that angularly pushing the second arm about the pivot via the push-pull cable moves the valve pin to the open position and angularly pulling the second arm about the pivot via the push-pull cable moves the valve pin to the closed position.
