Title: Hitoshi Okuyama: Innovator in Fuel Injection Technology
Introduction
Hitoshi Okuyama is a notable inventor based in Saitama-ken, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of fuel delivery systems.
Latest Patents
One of Okuyama's latest inventions is a plunger pump designed to discharge fuel through the reciprocation of a plunger. This innovative pump features metallic diaphragm type dampers at both the fuel inlet and outlet sides, which effectively reduce pressure pulsation. The design includes a pressure chamber for receiving fuel pressure, a back pressure chamber filled with gas, and a metallic diaphragm that separates these chambers. This configuration minimizes noise and vibration caused by pressure fluctuations, while the use of metallic diaphragms ensures high reliability and a long lifespan.
Another significant patent is the swirl type fuel injection valve. This valve consists of a guide hole, a valve seat, and an injection port, all formed coaxially on an elongated valve body. Pressurized fuel is introduced into the guide hole, where a valve element is slidably received. Inclined passages allow the pressurized fuel to flow in a swirling motion, enhancing the efficiency of fuel injection. When the valve element is fully lifted, an orifice is created to restrict the amount of fuel injected per unit time, optimizing performance.
