Title: The Innovations of Tomoji Ishikawa
Introduction
Tomoji Ishikawa is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of engineering, particularly in the development of high-pressure fuel pumps and solenoid-operated fuel injection valves. With a total of six patents to his name, Ishikawa's work has had a considerable impact on automotive technology.
Latest Patents
Ishikawa's latest patents include a high-pressure fuel pump and an assembly structure designed to decrease the initial axial force of a clamping bolt. This innovation prevents distortion of the sealing surface and the cylinder form. The high-pressure pump features an intermediate member that includes a cylinder body with a pressurizing chamber. This chamber is connected to a cylinder that accommodates a plunger, allowing fluid to be pressurized through the reciprocation of the plunger. Additionally, the clamping bolt has an exposed area at its axially central region, ensuring that the entire periphery is visible from both the cover and the flange.
Another significant patent is the solenoid-operated fuel injection valve. This valve consists of a container for fuel, a needle member that moves longitudinally within the container, and an electromagnetic controller with first and second magnetic circuits. These circuits allow for independent control of suction forces. The design enables variable injection rates by changing the area of the fuel flow passage as the needle member is moved by the suction forces.
