Abstract
A two-way electromagnet has an input port and a discharge port at opposing ends of a flow passage which is opened or closed by the drive of an electromagnet. The two-way electromagnetic valve operating portion or module includes an electromagnetic coil, a plunger adapted to be driven by the electromagnetic coil, a yoke fitted around a sleeve and a push rod fixed in the plunger. The valve portion or module includes an outer valve body in which the input port and a valve seat are formed, an inner valve body formed with a bore for receiving the leading end of the push rod therethrough and a passage communicating with the discharge port. The valve member is a ball arranged between the valve seat of the outer valve body and the inner valve body. The push rod is moved forward when the electromagnetic coil is deenergized to bring the ball into abutment against the valve seat to thereby close the input port. When the electromagnetic coil is energized, the push rod is moved backward to allow the ball to move out of the valve seat thereby opening the input port and establishing communication between the input port and the discharge port. Alternatively, the valve seat may be formed in the inner valve body.
