Control valve assemblies for hydraulic braking systems |
摘要 |
A control valve assembly for a vehicle dual hydraulic braking system in which hydraulic fluid from a distributor chamber can be supplied to one or both of a pair of outlets for connection to brakes on opposite sides of a vehicle. The assembly incorporates a pressure control valve operable to supply fluid under pressure to the chamber from an outlet for connection to a pressure source, irrespective of whether one or both of two separate brake-applying valves are to be operated, and a one-way valve is located on the upstream side of the pressure control valve to prevent flow in a reverse direction. A back-up piston works in a bore in communication with the chamber, and is provided to pressurize fluid in the chamber after an exhaust valve has closed and a pressure control valve has opened.
