Title: Innovator Tsuneo Niwa: Advancements in Solenoid Valve Technology

Introduction: Tsuneo Niwa, an esteemed inventor hailing from Komaki, Japan, is recognized for his innovative contributions to solenoid valve technology. With a background in engineering, he has developed a unique patent that addresses critical challenges in fluid control systems.

Latest Patents: Tsuneo Niwa holds a patent for a "Solenoid Valve with a 2-Part Fixed Core." This ingenious design allows the valve to handle corrosive control fluids while delivering an increased attraction force. The solenoid valve features a fixed core positioned within a wound coil, which extends through the lower surface of the coil. A plunger, which supports a valve sheet, is anchored by a plate spring beneath the fixed core. The valve sheet is typically pressed against the valve seat by the spring force, but when the coil is energized, it disengages from the seat, allowing fluid to flow. The innovative design includes two vertically coupled parts in the fixed core—an upper core made of high magnetic permeability material and a lower core crafted from corrosion-resistant material, vital for ensuring durability against harsh fluids.
