Anti-lock brake equipment solenoid valve

Abstract

The present invention relates to an ABS hydraulic control valve. The hydraulic control valve comprises: a modulator block; an inlet port arranged in the modulator block; a receiving unit arranged in the modulator block and communicating with the inlet port; an outlet port arranged in the modulator block and communicating with the receiving unit; a housing mounted on the receiving unit and having a coupling hole in a side thereof; an outlet hole arranged in the housing and communicating with the outlet port; an armature mounted on a side of the housing; a plunger coupled with the armature and having a projection at an end thereof, a valve seat arranged adjacent to the projection of the plunger and installed in the coupling hole of the housing; a chamber arranged within the valve seat; a hole connected to the chamber for adjusting flow rate; a compressive spring supported on a face of the hole and coupled to a side of the projection of the plunger; the projection being closely contacted/detached with/from the compressive spring; and a seal cup coupled to an outer periphery of the valve seat. The control valve is simply assembled, decreased in the number of components in the construction of an article, and advantageous in downsizing and reducing the weight. Further the manufacturing cost can be reduced. The flow path is formed by cutting the outer periphery of the valve seat and thus easily formed. The flow path can have a wide magnitude so that oil can smoothly flow without any pneumatic resistance.
