Title: Innovations by Toshio Yama

Introduction

Toshio Yama is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of hydraulic systems, particularly in automotive applications. With a total of 2 patents, Yama's work focuses on enhancing safety and efficiency in braking systems.

Latest Patents

Yama's latest patents include a Hydraulic Anti-Skid Device and an Anti-Skid Control Unit. The Hydraulic Anti-Skid Device features locking means that secure an expansion valve in a position allowing communication between the master cylinder and a brake unit when hydraulic fluid pressure is not generated by a pump. This innovation eliminates the need for a bypass valve and a differential valve, enabling air purging without an air bleed device. The Anti-Skid Control Unit incorporates a check valve that is integrally formed on one end of an expansion valve. This valve cuts communication between the master cylinder and the brake units when the hydraulic fluid pressure is reduced, either due to a signal from a computing circuit indicating a dangerously high rate of deceleration or the cessation of pressurized hydraulic fluid supply.
