  • Patent number: 3995652
    Abstract: A solenoid operated 3-way, 2-position directional control valve for use in an antiskid regulation system includes an armature controlled by a solenoid and is firmly connected to a valve spool movable in a bore. The valve spool enables an outlet port to wheel brake cylinders to communicate with a fluid source (master cylinder) or a reservoir. The valve spool is actuated by the pressure at the outlet port in the direction of the solenoid and in opposite direction by the pressure of the fluid source such that the valve spool assumes an intermediate equilibrium position between its two normally open and normally closed positions. In this equilibrium position the outlet port is blocked from both the fluid source and reservoir.
