Abstract
An electromagnetic valve having a flow passage opened and closed by the drive of an electromagnet. The electromagnetic opertor includes a casing, an electromagnetic coil, a plunger adapted to be driven by the electromagnetic coil, a sleeve for guiding the plunger, a yoke fitted around the sleeve and formed with an axially extending central portion and a notch in its outer circumference, and a push rod fixed to the plunger. The valve portion includes an outer valve body, having an input port and a discharge port, which is fixed to the casing of the electromagnet with a flange fitted over and mating with the raised central portion of the yoke. An inner valve body is mounted in the outer base and has an axial bore for receiving the push rod. A ball is interposed between the outer valve body and the inner valve body for opening or closing the passage of the valve, extending from the input port to the discharge port, by the drive of the push rod.
