PURPOSE: A solenoid valve for a brake system is provided to reduce the manufacturing costs by reducing work procedures with a simple structure. CONSTITUTION: A solenoid valve for a brake system(100) comprises a seat support member(110), a sleeve(120), a valve core(140), an opening and closing member(130), an armature(160), a return spring, and an opening spring(155). The seat support member comprises a flange(115) fixed on a modulator block(101). The bottom of the sleeve is fitted in the seat support member. The valve core is coupled to close the opened top of the sleeve. The top of the opening and closing member is positioned in the sleeve to longitudinally move in the seat support member. The armature is installed to longitudinally move in the sleeve and comprises a second opening and closing part(162) for opening and closing a second orifice(132). The return spring presses the armature toward the second orifice. The opening spring moves the opening and closing member towards the armature to open a first orifice. |
