Beschreibung
Zusammenfassung:	The present invention refers to a molten plastic delivery system comprising: a nozzle defining a nozzle channel having a downstream nozzle channel opening; a valve pin is reciprocable within the nozzle channel between a closed position and an open position; a bell crank having a first and second arms that are connected at and rotatable about a pivot, the first arm is coupled to the valve pin; a push-pull cable is coupled to the second arm 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. 具有推拉缆致动的熔融塑料递送系统。一种熔融塑料递送系统，包括：喷嘴，所述喷嘴限定喷嘴通道，所述喷嘴通道具有下游喷嘴通道开口；阀销，所述阀销可在喷嘴通道内在闭合位置和打开位置之间往复运动；钟形曲柄，该钟形曲柄具有第一臂和第二臂，该第一臂和该第二臂连接在枢轴处连接并且能够绕所述枢轴旋转，第一臂联接到阀销；推拉缆，所述推拉缆联接到第二臂，使得经由推拉缆绕所述枢轴对第二臂的角向推动将阀销移动到打开位置，并且经由推拉缆绕所述枢轴对第二臂的角向拉动将阀销移动到闭合位置。
