Title: The Innovative Contributions of Toshiyuki Suwa
Introduction
Toshiyuki Suwa is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of automotive technology, particularly in the development of vacuum and negative pressure boosters. With a total of 9 patents to his name, Suwa's work has had a considerable impact on vehicle safety and performance.
Latest Patents
One of Suwa's latest patents is a vacuum booster that incorporates a reaction force mechanism between an input rod and a valve cylinder connected to a booster piston. This design allows for a valve piston to be fitted onto an input piston, enabling it to slide forward from a predetermined retreat position. The valve piston is biased to return to the retreat position by a set spring, and a locking device is included to secure the valve piston at the valve cylinder. This innovation ensures that the atmosphere introduction valve seat remains open during emergency braking, thus eliminating delays in atmosphere introduction into the operating chamber.
Another significant patent is the negative pressure booster, which features a repulsion force mechanism among a valve cylinder, valve piston, and output rod. This mechanism includes a flexible piston positioned between the valve cylinder and the output rod, along with a repulsion force piston that faces the flexible piston. A spring is placed between the repulsion force piston and the valve piston, imposing a setup load in the direction of contraction. A stopper is also provided in the valve cylinder to support the front end of the valve piston before the spring reaches its limit of contraction.
