Title: Atsuya Okamoto: Innovator in Fuel Injection Technology
Introduction
Atsuya Okamoto is a prominent inventor based in Okazaki, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 12 patents. His innovative designs have advanced the efficiency and functionality of fuel injection systems.
Latest Patents
One of Okamoto's latest patents is a fuel injection valve that utilizes a fixed core to generate a magnetic attraction force when a coil is energized. This design features a movable core with an attracted surface that faces the attracting surface of the fixed core. When the movable core is attracted to the fixed core, it causes the valve body to open a nozzle hole. Additionally, a stopper member restricts the movement of the movable core, ensuring precise operation. The attracting and attracted surfaces are designed to extend annularly around the axis line of the fixed core, with a separation distance that increases toward the radially outer side.
Another notable patent is a fuel injection valve that includes a valve body, a fixed core, a movable core, a spring, and a cup. The movable core has two core contact surfaces: one that contacts the valve body and another that contacts the cup. This configuration creates a fuel storage chamber surrounded by the movable core, cup, and valve body, allowing for efficient fuel accumulation. The design also incorporates a communication groove that connects the inside and outside of the fuel storage chamber.
