Abstract
A hot runner system having a nozzle and a manifold seated against the nozzle. An actuator plate is spaced apart from the manifold by a support pad which surrounds a lower mouth of an actuator bore that extends through the actuator plate. A valve pin extends through the support pad and the manifold to a downstream end of the nozzle. A cylinder is received in the actuator bore from a rearward side of the actuator plate and a piston coupled to the valve pin is received in the cylinder from a forward end of the cylinder.
