Title: Toshiya Hayashi: Innovator in Pumping Apparatus Technology

Introduction

Toshiya Hayashi is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of automotive technology, particularly in the development of innovative pumping apparatuses. With a total of 4 patents to his name, Hayashi's work has had a considerable impact on automotive brake systems.

Latest Patents

One of Hayashi's latest patents is a rotating pumping apparatus with a seal mechanism. This apparatus is designed for use in automotive brake systems and features a sealing member and a pressure member. The sealing member is strategically placed around a pump drive shaft, while the pressure member includes a plate spring, a first rotation stopper, and a second rotation stopper. The first rotation stopper prevents the pressure member from rotating with the pump drive shaft, and the second rotation stopper engages the seal ring to keep the sealing member stationary. The plate spring ensures that the sealing member is pressed against a stopper wall of the pump casing, preventing axial movement.

Another significant patent is the rotary pump for braking devices. In this design, the curvature of the circular arc of the suction groove is larger than that of the discharge groove. This configuration allows for a shorter distance between the suction and discharge grooves in the radial direction, enhancing the total fluid pressure generated between them. Additionally, it reduces the contact surface pressure required by a second side plate, which is essential for obtaining a press-back force when in contact with the outer and inner rotors.
