ABSTRACT:
A manual/automatic brake valve of the OR configuration wherein either the servo command or the manual pedal force, whichever is the greatest, overpowers the other and is the exclusive controller of the brake pressure and springs are provided to generate a feel force during manual actuation. The feel force is independent of valve spool displacement as a result of the automatic servo input and as a result the feel force is relative to manual brake position and ignores brake force as a result of the servo command.
