Abstract
A hydraulic control valve for an Anti-lock Braking System (ABS) includes a modulator block having at least a housing, an inlet port, a receiving unit, and an outlet port. The housing is coupled to at least a plunger, an armature, and a coil body. The housing also has a coupling hole to receive a valve seat. Upon application of a current, a coil generates a magnetic field causing a plunger coupled with the armature to perform a reciprocating motion in which a projection of the plunger moves in contact with and separates from an aperture in the valve seat to adjust fluid flow. The hydraulic control valve also comprises fluid flow paths, provided in a space between the valve seat and the housing, which communicate with an outlet port. The hydraulic control valve accommodates at least a filter and a seal cup on the outer periphery of the valve seat.
