OIL-PRESSURE CONTROL VALVE FOR A.B.S. SYSTEM OF AUTOMOBILES

摘要

The valve is designed to perform hydraulic controlling of ABS(Anti-lock Brake System) of automobiles to prevent backflow of hydraulic force and increase/decrease the force to a wheel cylinder. The valve comprises: a pilot path (24) of the first port (15) located at one side of the first valve chamber (16); a piston (20a) having an inlet (24a) in front of a check valve (22) and an outlet (24b) supported by a spring (20); the second valve chamber (19) connected to an electro solenoid (18a); and the second port (17) located in front of a drain flow path (23) of the second valve chamber (19).
