发明名称 SOLENOID VALVE FOR BRAKE SYSTEM
摘要 PURPOSE: A solenoid valve for a brake system is provided to easily open and shut a valve although strong braking pressure is given to an inlet port of the valve by opening and shutting the valve in order by two stages. CONSTITUTION: A solenoid valve for a brake system comprises a hollow valve housing(31) with an inlet port and an outlet port; a hollow sleeve(32) coupled to the valve housing; a magnetic valve core(33) coupled with the other end of the sleeve; an armature(34) with a plunger portion extended into the valve housing; an exciting coil installed outside the valve core and the sleeve, to move the armature; a compensating spring(36) installed between the valve core and the armature, to advance the armature toward the valve housing when power source isn't applied to the exciting coil; a spool(41) to be moved inside the valve housing so that the outlet port is opened and shut in order by two stages if the armature moves; a hollow support member(42) coupled with the outer surface of the spool and fixed with the outer surface of the plunger portion of the armature; and a spool compensation spring(43) elastically supporting the spool. A passage is opened and shut orderly by two stages and therefore, the valve is easily opened and shut although strong braking pressure is given to the inlet port of the valve.
