てなることを特徴とする電磁弁。 An excitation coil is wound around the outer periphery of a cylindrical casing made of a non-magnetic material, and a fixed iron core with a circulation hole provided at the center of the axis is fitted into one end of the cylindrical casing, while the other end of the cylindrical casing is fitted with a fixed iron core. A movable core constituting the valve body is fitted with a valve seat having a valve hole at the center of the shaft, and a bottomed center hole made of a magnetic material and opening toward the fixed core is provided in the cylindrical casing. The movable iron core is fitted in a slidable manner, and a conical recess is provided on the inner end surface of the fixed iron core, and a conical protrusion is formed on the base end surface of the movable iron core opposite to the conical recess, and the movable iron core is opposed to the valve seat. The rear end of the movable core is formed into a tapered conical shape, and a communication hole is provided that opens in the conical surface of the rear end and communicates with the bottomed center hole, and A solenoid valve characterized in that a compression spring is interposed between the bottom and the center of a conical recess of a fixed iron core.
