Title: Kazuaki Koyanagi: Innovator in Fuel Injection Technology
Introduction
Kazuaki Koyanagi is a notable inventor based in Obu, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 5 patents. His innovative designs have advanced the efficiency and functionality of fuel injectors.
Latest Patents
Koyanagi's latest patents include a sophisticated fuel injector design. This fuel injector comprises a valve body with a fuel path, a valve seat fixed to the downstream end of the valve body, and a valve that opens and closes a fuel injection hole of the valve seat. The valve is housed within the valve body in a manner that allows for sliding. An armature is attached to the upstream end of the valve, while a valve closing element is connected to the downstream end. A core is positioned at the upstream side of the armature, with the downstream end surface of the core facing the upstream end surface of the armature. When the valve opens the fuel injection hole, these surfaces make contact. Additionally, a non-magnetic ring is placed at the outer circumference of the armature and the core, extending to the upstream side of the solenoid coil, which is wound directly around the outer circumference of the non-magnetic ring.
Another patent focuses on a fuel injector with a simplified part shape and assembly process. This design features a tubular core that attracts the armature of a valve by energizing a solenoid coil. An outside magnetic path forming member partially surrounds the solenoid coil, constituting a magnetic path along with the armature and the core. The outside magnetic path forming member includes an end plate with a mounting hole, allowing for easy positioning of the outside magnetic path forming member on the core.
