A solenoid valve of a brake system is provided to prevent oil from flowing out by closely combining the inside flow path extension unit. A solenoid valve of a brake system is composed of a valve core(50), a sleeve(30), an amateur(40), a valve sheet member, a returning spring(45), and a filter element(70). The valve core is inserted into the side of the sleeve. The amateur is arranged to be moved backward and forward in the sleeve. The valve sheet member includes a first orifice(24), an inside flow path(21), and an inside flow path extension unit(25). The first orifice is opened and closed by the armature at one side of the valve sheet member. The inside flow path is connected to the first orifice at the other side of the valve sheet member. The returning spring pressurizes the armature toward the first orifice. The filter member is combined to the valve sheet member. |
