Latest Patents
Hiramatsu holds a patent for a solenoid-operated valve designed for selecting one of two pressure sources. This invention features a stationary core that includes a cylindrical magnetic body, which is energized by an excitation current of a selected direction. The valve housing contains first and second magnet chambers that communicate with two pressure sources at either end of the stationary core. The design incorporates first and second permanent magnets, which are housed in the respective magnet chambers and are magnetized to poles opposite to those of the first and second pole faces. The first valve member, formed integrally with the first permanent magnet, closes a vent hole connected to the first pressure source when repelled from the first pole face. Similarly, the second valve member, formed with the second permanent magnet, closes a vent hole in the stationary core when attracted to the second pole face. Hiramatsu's patent represents a significant advancement in valve technology.
