Abstract

Improvements in valve assemblies for liquid pressure brake systems, characterized in that each set includes, a first pressure control valve included in a sub-system of the braking system, a second fluid pressure control valve included in another sub-system of the liquid-pressure braking system, means responsive to the fluid pressure at the outlet of the two valves, the means responsive to the pressure of the fluid cooperating with the two valves so that, if the pressure of the fluid at the outlet of one of the two valves exceeds the fluid pressure at the outlet of the other of the two valves by more than a predetermined amount the valve member of the other valve is separated from its corresponding valve seat by the action of the media sensitive to fluid pressure, until the load is balanced in the media sensitive to the fluid pressure.
