Abstract
A solenoid valve for an anti-lock brake system is disclosed which has two orifices and oil passages formed a magnetic core so that at the slip mode the amount of hydraulic oil transmitted to a wheel sylinder can be varied, its structure is simplified and its manufacture is facilitated. The solenoid valve includes a magnetic core,inserted into a bore,in a modulator,which has an inlet and outlet passages,and,and an invariable orifice,, a plunger,installed in the magnetic core,, and a piston,A installed in the inlet passage,. The piston,A has an eccentric hole,formed vertically passing through its interior and a groove,on its top surface, thus forming a variable orifice,along with a lower end of the invariable orifice,. The magnetic core,has a through hole,formed slanting upward. A lip seal,is formed between the outer periphery of the magnetic core 130 and the bore
