ABSTRACT:
A three way electromagnetic valve has a plunger provided with a small-diameter section, the diameter of which is smaller than the diameter of a plunger seat, so as to increase the sectional area of a fluid passage running between an output port and a discharge port. The inner wall surface of a ball holding section is provided with ball guides for guiding a ball. The diameter of the ball holding section is made larger than the diameter of the ball in order to secure the flow rate of a fluid in the ball holding section.
