Abstract

An anti-skid valve in an aircraft braking system achieving advantages by the application of hydraulic system pressure, rather than metered braking pressure, to the first stage of a two stage anti-skid valve. When the valve is not in use the quiescent flow tends to erode the first stage valve, thereby degrading performance. The present system shutoff valve eliminates this disadvantage by shutting off system pressure to the valve whenever the brakes are not in use, as indicated by the absence of metered braking pressure.
