Abstract: PURPOSE: A solenoid valve of a hydraulic brake is provided to efficiently conduct the magnetic flux induction and the sealing of the solenoid valve at the same time. CONSTITUTION: A wheel brakes by supplying oil to a wheel cylinder. The oil doesn't pass through a solenoid valve(100) and only pressure inside the wheel cylinder is increased. Upon releasing the brake or the locking state, the solenoid valve starts operating by current fed to a coil(320). Magnetic flux flows along a case(310) of a coil unit(300) through a magnet core(220) and fed to an electric agent(230). Then the magnetic flux finally flows to the case of the coil unit. The electric agent overcomes the resilient force of the spring and moves upward. An orifice channel(250) is open and the hydraulic inside the wheel cylinder is decelerated.
