Claim 9:
10. A solenoid valve comprising:
a plunger configured to be movable in two opposite directions;
a damper member inserted into the plunger and having at least a part protruding outward from the plunger; and
a pilot member positioned in a lower region of the plunger, the pilot member having a pilot flow path;
wherein the damper member comes into contact with the pilot member and closes the pilot flow path when the plunger moves downward by a predetermined distance toward the pilot member;
wherein an internal space is formed in a lower region of the plunger, the pilot member is inserted into the internal space, the plunger has an inner protrusion region protruding toward the internal space and formed on an inner surface that defines the internal space, and the pilot member has an outer protrusion region protruding outward and formed on a portion of the pilot member that is inserted into the internal space, the outer protrusion region being configured to interfere with the inner protrusion region; and
wherein a distance in a vertical direction between the damper member and a lowermost end of the outer protrusion region is shorter than a distance in the vertical direction between the damper member and an uppermost end of the inner protrusion region.
