ABSTRACT:
A fluid brake control system is disclosed having an improved emergency application and stability control device for use in association with a brake control pipe, emergency and auxiliary fluid reservoirs, a first quick action chamber, a brake cylinder, and emergency and service control valves. An improved emergency application and stability control valve is provided comprising a housing containing a differential abutment subject to actuation axially by differences in fluid pressures in respective brake pipe pressure and quick action control pressure chambers on opposite sides of the abutment. The control device has at least one ball poppet type valve on each side of the abutment that is spring biased toward a closed position and has an operating push rod longitudinally disposed between the associated valve and the abutment. The poppet valve on one side of the abutment is opened by movement of the abutment in one direction for permitting application of fluid from the emergency reservoir to the brake cylinder. The poppet valve on the other side of the abutment is opened by movement of the abutment in the opposite direction to permit charging of the first quick action chamber at a controlled rate from the brake pipe. A stabilizing spring is provided in the brake pipe pressure chamber biasing the abutment normally in a direction to close the poppet valve on said one side of the abutment and to open the poppet valve on the other side of the abutment.
