Patent ID: 8375985

Claim:
A solenoid valve for a brake system, comprising: a valve seat member having an inner passage provided through the valve seat member in a longitudinal direction thereof, an outer passage provided on an outer surface of the valve seat member in the longitudinal direction, and a seat portion having a first orifice above the inner passage, the seat portion being unitary with the valve seat member; an inlet deformable portion of a modulator block integral therewith; a sleeve including a flange portion coupled on the outer surface of the valve seat member, wherein the flange portion of the sleeve is fixed to the modulator block beneath the inlet deformable portion of the modulator block that interlocks with the flange portion; a valve core coupled to a portion of the sleeve, opposite to the flange portion, wherein the valve core includes a coupling recess disposed on an outer surface thereof, and the sleeve includes a latching portion formed by deformation of the sleeve, whereby the valve core is coupled to the sleeve by the latching portion being fitted into the coupling recess and latched by the coupling recess by the deformation of the sleeve; an armature slidably mounted in the sleeve, the armature having an opening/closing portion to open or close the first orifice; a restoring spring to press the armature toward the first orifice; and a filter member mounted in a longitudinal direction on the outer surface of the valve seat member, wherein the outer passage of the valve seat member is provided entirely along the outer surface of the valve seat member in a groove shape between the valve seat member and the sleeve.
