Patent abstract
An actuator for a hot runner has a piston and a valve pin holder threadably connected to the piston. The piston can be translated by fluid pressure and rotated by an electric motor. The valve pin holder is rotationally fixed, and therefore moves along the thread when the piston is rotated. A valve pin connected to the valve pin holder moves in response to fluid pressure and also in response to the electric motor rotating the piston.
