Latest Patents

One of Tamaki's latest patents focuses on a lightweight, low-cost throttle body and throttle valve. Both components are formed of resins, addressing the issue of excessively large gap formation. The design incorporates circumferentially oriented filler within the resin, which helps to equalize the radial linear expansion coefficient of the throttle valve with that of the bore. Additionally, grooves are formed on concentric circles in the throttle valve to enhance the orientation of the filler. This innovative approach allows for the creation of a throttle valve by impregnating an aggregate of circumferentially arranged filler with resin and curing it. Furthermore, a rib is strategically placed near the throttle shaft to control molding shrinkage, ensuring minimal roundness of the bore.
