Patent ID: 7866625

Claim:
A solenoid valve for a brake system, comprising: a valve seat member integrally formed with a seat portion having a first orifice; an opening/closing member slidably installed in the valve seat member, the opening/closing member having an inner passage formed through the opening/closing member, an outer passage formed at an outer surface of the opening/closing member, a second orifice formed at one end of the opening/closing member, the second orifice having a smaller diameter than that of the first orifice, and a first opening/closing portion formed at the other end of the opening/closing member to open or close the first orifice; an opening spring to move the opening/closing member, for opening of the first orifice; a sleeve having a first end coupled to an outer surface of the valve seat member and a flange formed at the first end so as to be fixed to a modulator block; a valve core coupled to a second end of the sleeve, opposite to the first end of the sleeve; an armature slidably mounted in the sleeve, the armature having a second opening/closing portion to open or close the second orifice; and a restoring spring to press the armature toward the second orifice, wherein a portion of the modulator block is deformed to cover the flange of the sleeve, so as to fix the sleeve, wherein the valve seat member includes a first coupling recess formed at an outer surface thereof, for coupling of the sleeve, and the sleeve includes a first latching portion to be fitted into the first coupling recess and latched by the first coupling recess by deformation of the sleeve.
