Claims

[Claims for Utility Model Registration] A first pressure chamber with which a high-pressure flow path communicates is formed in one axial direction, and a second pressure chamber with which a pair of low-pressure flow paths communicate is formed in the other axial direction, and , a cylindrical valve body forming a communication port that communicates the first and second pressure chambers; and a valve body disposed movably in the axial direction within the first pressure chamber of the valve body and communicating with one end surface in the axial direction. A first valve body having a pilot port communicating with the other end face facing the mouth and opening and closing the communication port; and a first valve body disposed movably in the axial direction in the second pressure chamber of the valve body, and the communication port a second valve body that has a communication path that communicates with one of the low-pressure flow paths and opens and closes the other low-pressure flow path; a spring that biases the second valve body in the opening direction; A three-way solenoid valve comprising: an electromagnet provided in a plunger with a valve portion for opening and closing an opening at one end of a pilot port of a valve body;
