Title: Innovations of Yoshiyuki Hiratsuka in Brake Booster Technology

Introduction

Yoshiyuki Hiratsuka is a notable inventor based in Saitama-ken, Japan. He has made significant contributions to the field of automotive technology, particularly in brake systems. His innovative approach has led to the development of a unique brake booster design that enhances vehicle safety and performance.

Latest Patents

Hiratsuka holds a patent for a brake booster that features a first vacuum valve seat formed on a valve body and a second vacuum valve seat on a tubular member. This tubular member is slidably mounted on the valve body. A lever member is positioned between the tubular member and a valve plunger. When the valve plunger strokes through a specified distance relative to the valve body, the lever member moves angularly, retracting the tubular member rearward. This mechanism allows for a greater opening of the atmosphere valve during quick brake pedal depressions, resulting in an increased output from the brake booster. This innovation enables a rapid response to sudden braking, enhancing overall vehicle safety.
