Title: Isao Matsuno: Innovator in Vehicle Braking Systems
Introduction
Isao Matsuno is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of vehicle braking systems, holding a total of 13 patents. His innovative designs focus on enhancing the efficiency and safety of braking mechanisms in vehicles.
Latest Patents
Matsuno's latest patents include a sophisticated vehicle braking system that features a hydraulic booster. This system applies output hydraulic pressure from a hydraulic power source to a boosted hydraulic pressure chamber. The design includes a control piston that balances the reaction force generated by the hydraulic pressure with the brake operating input. The boosted hydraulic pressure chamber is strategically positioned to face the rear of a master piston within a master cylinder. Additionally, a brake stroke simulator is installed between the brake operating member and the control piston. The hydraulic booster is equipped with a backup piston that can directly push the master piston in response to the operation of the brake operating member when hydraulic pressure decreases. This innovative approach allows for a more efficient braking process.
Another patent describes a vehicle braking system where a backup piston pushes a master piston directly from behind when the hydraulic pressure of the boosted hydraulic pressure chamber decreases. The backup piston features a piston body that is slidably fitted in a casing, along with a pusher that extends to the front end of the piston body. This configuration ensures that the volume increase in the boosted hydraulic pressure chamber is equal to the volume decrease in the input chamber, thereby preventing an increase in hydraulic pressure during the forward movement of the backup piston.
