Title: Masahiro Shimada: Innovator in Fluid Pressure Technology
Introduction
Masahiro Shimada is a notable inventor based in Higashimatsuyama, Japan. He has made significant contributions to the field of fluid pressure technology, holding a total of 13 patents. His innovative designs have advanced the functionality and efficiency of various mechanical systems.
Latest Patents
One of Shimada's latest patents is a fluid pressure boosting device. This device features a control valve composed of a supply valve and a discharge valve. The supply valve includes an annular valve cone of a poppet type and a first valve seat, while the discharge valve comprises a similar structure with a second valve seat. Inside the rear end portion of a primary piston of a master cylinder, a reaction disk made of elastic material, such as rubber, is fitted. An input shaft penetrating the control valve is arranged to confront the reaction disk in the inoperative state, allowing for a predetermined space. In the operative state, the end of the input shaft contacts the reaction disk, transmitting a reaction force. The design includes annular passages for discharging hydraulic fluid, resulting in a simple structure that enhances the jumping characteristic of the fluid pressure boosting device.
Another significant patent is a brake system that incorporates a brake operating means, such as a brake pedal, for executing braking operations. This system features a fluid variable stroke means that variably controls the stroke of the brake operating means using fluid. The braking force output means is actuated by the operation of the brake operating means to produce the necessary braking forces. By manipulating the brake operating means, the stroke can be adjusted, ensuring a proper pedal stroke is achieved.
