Title: Modulator of an antiskid device for air brakes

Abstract: The modulator of an antiskid device for air brakes of the type wherein a throttling electric signal is produced to change the braking pressure applied by brake actuators from a rapid increase state to a slow increase state before the braking pressure reaches a pressure increase target value, a pressure reducing electric signal is produced by rapidly decrease the braking pressure when the braking pressure has reached the pressure increase target value, and a throttling electric signal is produced again to change the braking pressure from the rapid decrease state to a slow decrease state before the braking pressure reaches a pressure decrease target value comprises a first solenoid assembly, a second solenoid assembly, a first pilot valve assembly, a second pilot valve assembly and a main valve assembly.
