Latest Patents

Okuyama holds a patent for a vehicular brake holding system. This system features a brake booster designed to maintain braking action even when the brake pedal is released. The mechanism includes a low-pressure chamber and a variable pressure chamber separated by a diaphragm, which moves the output shaft to the brake cylinder. A valve mechanism, controlled mechanically by the brake pedal, switches the communication passage between the low and variable pressure chambers and an atmospheric pressure passage from the variable pressure chamber to the exterior. A first solenoid valve can close the communication passage between the low and variable pressure chambers, allowing for braking to be held regardless of the brake pedal position. Additionally, a second solenoid valve controls a passage between the variable pressure chamber and the low-pressure source, enabling a gentle release of braking.
