Latest Patents

Ozawa holds a patent for a multi-protection valve. The primary objective of this invention is to ensure that a vehicle can continue to operate even when an air compressor connected to an input port fails, causing air leakage. The multi-protection valve is designed to prevent air from leaking from the parking brake circuit through a bleed air flow path. It features a communication passage that connects the input chamber to the service output port, bypassing the pressure control valve. This passage includes a check valve to prevent backflow and a throttle to regulate air flow. Additionally, the valve incorporates a bleed air flow path that connects the input chamber to the parking output port, equipped with a second check valve to prevent air from flowing back into the input chamber. A third check valve is also included to prevent air from flowing from the input chamber to the input port.
