Abstract
A reduction apparatus mainly comprises a casing mounted on a valve body, an input shaft, an external gear, an internal gear capable of engaging the external gear, a rotary member connected to the internal gear to transmit the torque from the same to a valve stem, and pin assemblies for preventing the external gear from rotating on its own shaft, while external gear revolves about the other shaft without rotating on its own axis, whereby the internal gear having a slightly larger number of teeth is given rotation due to the difference in number of teeth of both gears, and the rotation of the input shaft is transmitted to the valve stem with its speed reduced.
