Latest Patents

Tomohiko Iida holds a patent for a damping force adjustable shock absorber. This invention allows for improved functionality when the shock absorber operates in a soft mode. When the piston performs a compression stroke and the piston speed falls within an ultra-low speed range, communication between the upper cylinder chamber and the reservoir is interrupted by an ultra-low speed valve. This interruption enables the expansion of oil liquid in the upper cylinder chamber, generating a differential pressure that opens the compression-side ultra-low speed valve. As a result, a damping force with specific valve characteristics can be achieved, enhancing the overall performance of the shock absorber.
