Claims19
A noise reduction member, which is interposed between a sleeve including a cylindrical shape and an armature provided in the sleeve so as to be movable upward or downward, the noise reduction member being configured to reduce noise that occurs in the event of a collision between the sleeve and the armature, the noise reduction member comprising:
- a support portion accommodated and supported in the armature;
- and
- a damper portion having a circular plate shape and protruding and extending from the support portion toward the sleeve, wherein the damper portion has a discharge flow path formed along a surface of the damper portion facing the sleeve and more recessed than a flat surface positioned at a center of the damper portion and facing the sleeve.
A solenoid valve for a brake system, the solenoid valve comprising:
- a valve core having an inlet and an outlet;
- a sleeve including a cylindrical shape coupled to one side of the valve core;
- an armature provided in the sleeve so as to be movable upward or downward;
- a plunger provided in the valve core and configured to open or close the inlet of the valve core in accordance with an upward or downward movement of the armature;
- and
- a noise reduction member accommodated in the armature and configured to reduce noise that occurs because of impact by the sleeve when the armature moves upward or downward,
- wherein the noise reduction member comprises:
- a support portion accommodated and supported in the armature;
- and
- a damper portion having a circular plate shape and protruding and extending from the support portion toward the sleeve, wherein the damper portion has a discharge flow path formed along a surface of the damper portion facing the sleeve and more recessed than a flat surface positioned at a center of the damper portion and facing the sleeve.
