Latest Patents
One of Nakamaru's key inventions is a liquid sealed vibration isolating device. This device features an elastic partition member that is integrally equipped with a relief valve. The relief valve opens and closes a leak passage to suppress the generation of the cavitation phenomenon. A pair of relief valves is designed in a crescent shape on the outer circumferential side of the movable diaphragm section, positioned in opposed relation. The crescent shape is formed by an inner circumferential side of elliptical arc shape and an outer circumferential side of circular arc shape. The valve length of the relief valve varies in the longitudinal direction, with the middle portion being the largest. This design allows for easy deformation when extraordinary vibrations are inputted. The end portions of the relief valve are short in valve length and high in rigidity, which helps prevent leaks during normal vibrations. Nakamaru holds 1 patent for this innovative device.
