ABSTRACT:
An electro-pneumatic brake system in which an electric brake demand signal controls the energization of a stepping motor. The shaft of the motor is threadedly engaged with a captive nut which bears against an abutment carried by a brake controlling valve, the opening of which determines brake actuating pressure downstream of the valve. Rotation of the motor therefore directly controls the brake pressure by movement of the valve.
