Title: Tomoharu Murakami: Innovator in Valve Technology
Introduction
Tomoharu Murakami is a distinguished inventor based in Tokyo, Japan. He has made significant contributions to the field of valve technology, holding a total of 4 patents. His innovative designs have enhanced the functionality and efficiency of various hydraulic systems.
Latest Patents
One of his latest patents is a leaf valve structure. This invention comprises an annular valve seat and a leaf that is seated on the valve seat under a predetermined elastic supporting force against the pressure of a working fluid. A recessed depression portion is formed in the valve seat, allowing the pressure of the working fluid to act more effectively on the seating surface between the valve seat and the leaf valve. This design suppresses the effect of surface adsorption force on the cracking pressure, enabling the leaf valve to lift under stable conditions.
Another notable patent is the check seal structure for hydraulic shock absorbers. This check seal is designed to discharge working oil scraped off a piston rod into an oil pool of a hydraulic shock absorber. The check seal features an annular seat surface and an annular lip that is seated resiliently on the seat surface. By introducing pressure to the annular groove, the check seal demonstrates high working oil discharging and sealing performance.
