Latest Patents

One of his latest inventions is a rotary damper. This rotary damper is designed with a unique structure that includes housings containing silicon oil. A rotor with a resistive portion moves through the silicon oil, which is housed within the housings. An O-ring is incorporated to prevent any leakage of the silicon oil between the axial portion and the housing. The design features multiple arc-like through-bores on a concentric circle, along with depressed grooves that communicate with these through-bores. This innovative assembly prevents excessive compression of air mixed into the housing, thereby minimizing noise during bi-directional rotation of the rotor.
