Ryoichi Tada is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 4 patents. His work focuses on developing advanced electromagnetic fuel injection valves that enhance the efficiency and performance of internal combustion engines.

Latest Patents

One of Tada's latest inventions is an electromagnetic fuel injection valve designed to prevent fuel bubbles from accumulating at the downstream side of the valve's stopper plate. This innovation ensures smooth fuel injection by incorporating a needle with a valve head that opens and closes a valve seat. The valve also features an electromagnetic coil portion that actuates the needle and a contact portion located downstream of the stopper plate. The stopper plate is designed with a notch to accommodate the needle and bubble discharge surfaces that direct bubbles produced at the downstream side toward the upstream side, facilitating smooth fuel flow.

Another significant patent by Tada is an electromagnetic fuel injection valve specifically for internal combustion engines. This valve includes a valve body with a valve seat and a valve member that moves within the valve body, controlled by an electromagnetic actuator. The valve member has an abutting part that can either interrupt or permit the supply of fuel to the engine. Notably, the metering portion of the valve member cooperates with the valve seat to create a fuel metering gap when in the open position, ensuring that the metering portion remains immersed in fuel even when the valve is closed.
