Latest Patents

Among his latest patents is the Torque Rod, which features an arm portion and a ring portion formed on each end of the arm. This design incorporates a rubber bushing that is integrally provided with the ring portion. The arm portion is crafted from a material that has a lower specific gravity than iron, enhancing its functionality. Additionally, a weight is strategically placed in a portion of the rubber bushing, excluding the principal spring portion. This principal spring portion is designed to absorb vibrations and is formed by an elastic arm that extends radially outward from an inner cylinder located at the center of the rubber bushing. An aperture serves as a separation space between the elastic arm portion and the ring portion.

Another significant patent is the Liquid Sealed Vibration Isolating Device. This device features an elastically movable diaphragm that prevents elastic deformation of a relief valve, thereby achieving high damping while avoiding cavitation phenomena. The relief valve is integrated into the elastic movable diaphragm, which is arranged in a partition member to control a leak passage and prevent cavitation. The relief valve is designed with a thicker structure and includes an opening and closing adjustment groove at the base of its inclined wall, facilitating its operation.
