Latest Patents

Akiko Kosaka holds a patent for a solenoid valve with a two-part fixed core. This solenoid valve is designed to manage corrosive control fluids while developing an increased attraction force. The design features a fixed core located in a wound coil, which protrudes through the lower surface of the coil. A plunger holding a valve sheet is supported by a plate spring under the fixed core. The valve sheet is normally retained in contact with a valve seat by the spring force of the plate spring. When the coil is energized, the valve sheet separates from the valve seat against the spring force. The fixed core consists of two vertically coupled parts, with the upper part being a first fixed core made of a material with high magnetic permeability, and the lower part being a second fixed core made of a corrosion-resistant material.
