Latest Patents

One of his latest patents is a railway vehicle body tilting system. This system features a height control valve that manages the supply and discharge of compressed air to an air spring via an actuator. Additionally, it includes an auxiliary control valve that allows for the tilting of the car body by supplying compressed air to the air spring. A backup valve is also integrated to switch connections between the height control valve and the auxiliary control valve. Each vehicle in a train is equipped with a controller that monitors the operation of linked controllers. In the event of a fault, the malfunctioning controller's control is terminated, allowing a normal controller to manage the backup valve.

Another significant invention is the vehicle-body inclination device, which utilizes a double-layer three-way valve. This device comprises individual inclination units corresponding to air springs and a control unit. The inclination units can effectively manage the supply or release of air to the air springs by operating a control valve and a large-capacity valve. The control valve features a two-layer structure that enhances its functionality.
