A solenoid valve, comprising:
- a valve core formed with an inlet and an outlet;
- a valve dome sealing one end of the valve core;
- an armature provided inside the valve dome to be able to advance and retreat;
- and
- a plunger opening and closing the inlet of the valve core according to the advance and retreat of the armature,
- wherein the armature includes:
- a receiving groove recessed in an upper surface;
- a buffering member provided between the armature and the valve dome;
- and
- a damping spring received in the receiving groove so that an upper surface of the buffering member is in close contact with the valve dome and elastically supporting the buffering member to the valve dome.
A method of operating a solenoid valve, comprising:
- a valve core formed with an inlet and an outlet;
- a valve dome sealing one end of the valve core;
- an armature provided inside the valve dome to be able to advance and retreat;
- and
- a plunger opening and closing the inlet of the valve core according to the advance and retreat of the armature,
- wherein when the armature moves downward and moves away from the valve dome, a buffering member provided in a receiving groove recessed in an upper surface of the armature is elastically supported by a damping spring received in the receiving groove and whose upper surface is in close contact with the valve dome, and
- when the armature moves upward and approaches the valve dome, the buffering member slides in the receiving groove so that the upper surface of the armature is in contact with a lower surface of the buffering member.
