Abstract
A hydraulic braking system including hydraulically operated brakes and a hydraulic relay valve for controlling the operation of the brakes in response to a mechanical input. The relay valve includes a metering valve having a medial and distal pair of axially-aligned lands with different diameters, defining an annular chamber between each medial and distal land. A modulator is included to provide a skid control capability. The modulator is hydraulically connected to one of the annular chambers, with system hydraulic pressure being provided to the other. This enables the modulator to vary the position of the metering valve as needed to prevent skidding of the wheels being braked.
