ABSTRACT:
The invention is generally described as a housing having an inlet port for receiving brake fluid and two opposing outlet ports for delivering the fluid to brake cylinders. A fluid screw designed to seal either outlet port is provided on an actuator having a screw mounting and an actuator leg. Between the screw mounting and the actuator leg is a pivot holding the actuator. The movement of the actuator on this pivot is controlled by the movement of the actuator leg which is in turn controlled by the movement of a sliding armature which moves in a channel defined by the housing. The armature movement is, in turn, controlled by two opposing solenoids on either side of the channel. Springs bias the armature back to a central position. The armatures are controlled by a manual switch available to the operator.
