Claims

[Claims for Utility Model Registration] A first valve seat 7 for communicating the input port and the output port and a second valve seat 8 for communicating the output port and the discharge port are arranged in the valve body 1,
First and second valve bodies 14 and 19 for opening and closing the first and second valve seats 7 and 8 are arranged,
When the movable iron core 12 is returned to its original position by the urging force of the return spring 15, the first valve body 14
When the valve seat 7 is closed and the second valve body 19 opens the second valve seat 8, and the movable core 12 is attracted to the fixed core 9 as the coil 10 is energized, the first valve body 14 is closed. While opening the first valve seat 7, the second valve body 1
9 is configured to close the second valve seat 8, and between the second valve body 19 and the valve body 1, the second valve body 19 is placed in the closed position of the second valve seat 8. A valve-closing spring 20 is interposed to bias the second valve body 19 toward the valve-closing spring 20 as the movable core 12 is attracted.
When the second valve seat 8 is moved to the valve closing position by the biasing force of A directional control valve characterized in that the valve body 1 is provided with a release member 22 so as to engage with the valve body 19 and release the urging force of the valve-closing spring 20 against the second valve body 19.
