Latest Patents

Sioda holds a patent for a "Reduction apparatus for opening and closing a valve." This apparatus primarily consists of a casing mounted on a valve body, an input shaft, an external gear, and an internal gear that engages with the external gear. The design includes a rotary member connected to the internal gear, which transmits torque to a valve stem. Additionally, pin assemblies are incorporated to prevent the external gear from rotating on its own shaft. The unique mechanism allows the internal gear, which has a slightly larger number of teeth, to rotate due to the difference in the number of teeth between both gears. This innovative design effectively reduces the speed of the input shaft as it is transmitted to the valve stem.
