Abstract
A braking control system comprising a first source of pressurized fluid (), a second source of pressurized fluid (), a modulator (), a brake actuator (), and a plurality of valves (), the modulator () having a supply inlet () which may be connected to either of the sources of pressurized fluid via a first fluid flow line which extends between a first one of the valves () and the supply inlet (), and a control inlet () which may be connected to either of the sources of pressurized fluid via a second fluid flow line and a second one of the valves (), a delivery port () which is connected an inlet () of the actuator (), and an exhaust outlet () which vents to a low pressure region, the modulator () being operable to move between a build position in which flow of fluid from the supply inlet () to the delivery port () is permitted while flow of fluid through the exhaust outlet () is substantially prevented, and an exhaust position in which flow of fluid between the delivery port () and the exhaust outlet () is permitted, while flow of fluid through the supply inlet () is substantially prevented, wherein a portion of the fluid flow line connecting the second source of pressurized fluid () to the first valve () also provides a proportion of the connection between the second source of pressurized fluid () and the second valve ().
