Abstract
A solenoid valve for brake system includes a valve housing installed in a modulator block, and having an oil flow path; a valve seat installed in the inside of the valve housing, and forming an orifice; an armature configured to move up and down by a magnet core in the valve housing, and to open or close the orifice; a sleeve coupled with the valve housing, and accommodating the armature therein; a restoring spring configured to provide an elastic restoring force to the armature to close the orifice normally; and a damper member interposed between the magnet core and the armature.
Claims11
A solenoid valve for a brake system comprising:
- a valve housing disposed in a modulator block, and having an oil flow path;
- a valve seat disposed in an inside of the valve housing, and having an orifice;
- an armature configured to move up and down in the valve housing by a magnet core to open or close the orifice;
- a sleeve coupled with the valve housing, and accommodating the armature therein;
- a restoring spring configured to provide an elastic restoring force to the armature to close the orifice normally;
- and
- a damper member interposed between the magnet core and the armature and spaced apart from the restoring spring, the damper member being a separate member from the armature,
- wherein the armature having a large diameter portion and a small diameter portion to form a dent portion, the dent portion having a first surface on which the damper member is disposed,
- an inner circumferential surface of the damper member is disposed outwardly of an outer circumferential surface of the small diameter portion in a radial direction,
- a thickness of the damper member in a first direction is greater than a depth of the dent portion, the first direction being defined as a direction from a top edge of the armature to the first surface of the dent portion and the depth of the dent portion being defined as a distance from the top edge of the armature to the first surface of the dent portion, and
- the first surface of the dent portion extends to an outer circumferential surface of the large diameter portion of the armature to be opened in the radial direction.
