PURPOSE: A purge control solenoid valve is provided to improve the operation stability of the purge control solenoid valve by improving a magnetic force applied between a core and an armature. CONSTITUTION: A purge control solenoid valve(1) comprises a chamber(100), an armature(200), a valve member(300), a core(400), a magnetic force distribution part(500), and a magnetic force reinforcement part(600). A pressure control room(120) is formed inside the chamber. A passage(110) is extended from the pressure control room to the outside of the chamber. The armature reciprocates against the chamber according to the formation of a magnetic force. The valve member is coupled to the armature to open and close the passage according to the reciprocating motion of the armature. The core exits according to the supply of current to generate the magnetic force by which the armature is linearly pulled. The magnetic force distribution part generates the magnetic force vertical to the pulled direction of the armature. The magnetic force reinforcement part is formed in the inner circumference of the armature and is attached to or separated from the end of the magnetic force distribution part. |
