Abstract: A brake traction control valve is disclosed. The brake traction control valve includes a valve core, a shell, an armature, an exciting coil, a plunger, and a return spring. The valve core has an inlet to allow inside and outside of the valve core to communicate with each other, and a valve seat provided with an orifice therein. The shell having a dome plus cylinder shape is coupled to the valve core to cover one end of the valve core. The armature is placed in the shell to move forward and backward. The exciting coil is placed around the shell to cause the armature to move forward and backward. The plunger is placed in the valve core to move forward and backward to selectively open and dose the orifice while moving forward and backward by the armature. The return spring returns the plunger and the armature to open the orifice. The plunger includes a first body brought into contact with the armature, a second body connected to one end of the first body to move forward and backward so as to selectively open and close the orifice, and a relief spring provided between the first and second bodies so that the second body is pushed by oil pressure when the oil pressure increases above predetermined pressure.

Abstract: A pump of an electronically-controlled brake system including a bore formed in a modulator block to communicate with inlet and outlet ports formed in the modulator block, a piston connected to a spindle of a motor arranged at one end of the bore, and arranged in the bore such that the piston reciprocates in the bore, and a cover coupled to the other end of the bore to define a compression chamber between the cover and an end of the piston facing the cover. The compression chamber communicates with the outlet port. The pump further includes an outlet valve to open and close the outlet port to allow oil in the compression chamber to be discharged from the compression chamber, an inlet passage formed in the cover to transfer oil in the inlet port to the compression chamber, and an inlet valve arranged in the compression chamber at an outlet of the inlet passage, and fixed to the cover to open and close the inlet passage. The inlet valve operates in opposite to the outlet valve. The inlet valve has a valve opening/closing member to selectively come into contact with a valve seat provided at the cover. Since the inlet valve is fixed to the cover, the valve opening/closing member can be rapidly moved away from the valve seat without being restrained by the piston. Accordingly, the filling rate of oil in the compression chamber is enhanced.
