Title: Blending valve for electro-pneumatic brakes

Abstract: An electro-pneumatic brake valve includes counteracting torque motors which rotate a cam in response to friction brake pressure, dynamic braking effort and/or an electrical control signal. The cam actuates switching elements to apply or release the friction brakes via a pair of solenoid actuated valves which control fluid flow from the valve inlet to the friction brake actuators and from the friction brake actuators to vent.
