<p>PURPOSE:To enable the opening or closing of two ports by one solenoid valve, by energizing two valve bodies which open or close two ports in the same direction respectively through respective energizing means, and further providing a moving element to be moved by a solenoid coil between two valve bodies. CONSTITUTION:When a current is not passed through a solenoid coil 26, the first valve body 4 opens the first outlet port 2 by the energizing force of the first coil spring 15, and further the second valve body 5 receiving the energizing force of the first coil spring 15 via a moving element 6 opens the second outlet port 3. On the other hand, when the solenoid coil 26 is magnetized, finally in the state in which the moving element 6 has moved at its maximum, the first valve body 4 is brought in contact with the first flow passage shut-off surface 28 to close the first outlet port 2, and this state is maintained by a magnetic attraction force of the solenoid coil 26. And the second valve body 5 is also maintained in such a state that the second outlet port 3 is closed by the energizing force of the second coil spring 24.</p> |
