Abstract:
An electromagnetic valve includes a valve body, a valve element, a movable iron core, a guide tube, a coil, a yoke, and a fixed iron core. The valve body includes a fluid flow path. The valve element is movable and seated on a valve seat provided in the fluid flow path of the valve body. The movable iron core moves the valve element with respect to the valve seat. The guide tube is cylindrical and movably supports the movable iron core. The coil is mounted on an outer periphery of the guide tube. The yoke covers an outside of the coil and forms a magnetic circuit. The fixed iron core is provided facing the movable iron core and attracts the movable iron core by energization of the coil. The valve body is coupled to the guide tube on one opening end side of the guide tube, and the fixed iron core is provided on an other end side of the guide tube with a clearance spaced from an inside of the guide tube. One end of the yoke is coupled to the fixed iron core, and the valve body is coupled to an other end of the yoke.
