Latest Patents
Oyamada's latest patents include a slide bearing device and a throttle system. The slide bearing device is designed to achieve a low friction condition from the early stages of operation. It consists of a bearing, a shaft supported by the bearing, and a gas supply section that provides a dry gas to the bearing slide section. The bearing's slide surface is made from a resin composite material, which combines a carbon material with resin. The shaft, made of metal, features grooves on its slide surface that extend in various directions, enhancing its functionality.
The throttle system aims to minimize air leakage from the air cleaner side into the engine when the throttle valve is closed. This is achieved by installing a seal material in the air passage, which runs from the upstream side of the suction passage through various gaps and reaches the downstream side of the suction passage. This innovative design helps improve engine efficiency.
