Abstract:
A foot control valve assembly for operating a vehicle brake system that includes brake chambers associated with wheels of the associated vehicle comprising:a foot pedal/treadle adapted to be selectively actuated by a vehicle operator; a first control valve operatively associated with the foot pedal/treadle for selectively delivering fluid pressure to and exhausting fluid pressure from brake chambers in response to actuation and deactuation of the foot pedal/treadle; an actuator operatively interposed between the foot pedal/treadle and the first control valve for activating the control valve independently of the foot pedal/treadle; a port that communicates between the actuator and the control valve, said port being adapted to receive the fluid pressure; and a second control valve that controls delivery of said pressure to the port; wherein the actuator activates the first control valve in response to said delivery of fluid pressure to the port.
