ABSTRACT:
A 3-position 3-way solenoid valve for anti-lock brake system is disclosed having a hinge structure. The solenoid valve includes a cylindrical housing and two covers hermetically coupled to both ends of the housing. The housing and two covers define an inner chamber which is partitioned into first and second chambers by a barrier, and first to third ports are communicated with the first chamber. The second chamber contains an armature, a solenoid assembly and a core, and the armature is fixed to a push rod which extends into the first chamber through a barrier hole. An end of the push rod in the first chamber is fitted to a ball slider within which a ball is included interposing a first spring. A second spring interposes between the cover defining the first chamber and one end of the ball slider. A step is formed on the outer wall of the ball slider. A valve lever extends substantially parallel with the ball slider to be caught with the step. A spool is fixed to one end of the valve lever in parallel with the valve lever. The valve lever is connected to a supporting rod by a pin to rock both ends of the valve lever, and the supporting rod is fixed to the cover. A third spring is disposed between the valve lever and the cover to be coaxial with the ball slider.
