Abstract
A pilot valve for effecting a control action selectively in response to the departures of the fluid pressure of a monitored fluid above or below a desired norm. Two axially spaced control fluid inlet ports in the valve body communicate with a valve chamber and a radially disposed fluid outlet port is located intermediate the two fluid inlet ports. Application of fluid to one fluid inlet port will result in the valve responding to an increase in fluid pressure above the desired norm while the application of fluid to the other port will result in the valve responding to a decrease in the monitored fluid pressure from the desired norm. Flow of control fluid from the selected inlet port to the outlet port is controlled by a spring biased spool valve which is axially shiftable within the central valve chamber by a piston responsive to the monitored fluid pressure.
