ABSTRACT:
An empty and load air brake control apparatus for railroad freight cars, for applying full braking forces to the car wheels when the car is riding loaded, but for applying reduced braking forces to the car wheels that are at appropriate force levels when the car rides empty, in which in addition to the conventional brake pipe, AB or ABD control valve, the auxiliary and emergency reservors, the brake cylinder, and the retaining valve, are included a special load sensing device and a modulating valve for supplying full braking air pressures to the brake cylinder when the car rides loaded and reduced braking air pressures to the brake cylinder when the car rides empty. The components of the apparatus are arranged and connected so that the load sensing device controls the operation of the modulating valve to supply the braking air to the brake cylinder that is appropriate for either loaded or empty braking, while providing for full braking air release at the retaining valve to the exclusion of the load sensing device, even when rock and roll are occasioned.
The arrangement is such that once the control apparatus is set to provide for the appropriate car braking, as sensed by the load sensing device, no amount of rock and roll can change the setting to loaded car braking where the car is riding empty or vice versa.
