Latest Patents
Among his latest inventions is the solenoid-controlled valve. This device features first and second valve bodies that are axially movable within a cylinder bore. A first spring is positioned between the valve end and the first valve body, while a second spring is interposed between the two valve bodies. The electromagnetic force generating device includes a movable member that facilitates the coordinated movement of the two valve bodies. The valve's opening and closing modes can be adjusted in multiple stages based on the displacement of the movable member. Additionally, a restricting portion limits the relative displacement of the two valve bodies, ensuring that the influence of the second spring's urging force on the electromagnetic device's driving force is nullified in the final stage of operation.
Another notable invention is the motor-driven brake apparatus. This system incorporates a motor and a ball screw that transforms the motor's rotational motion into the linear motion of a screw member. A position detector is employed to monitor the stroke position of the screw member. The controller adjusts the motor's operation based on the position detector's feedback, allowing for the modification of the clearance between the inner and outer pads and the disk, depending on the vehicle's running conditions.
