ABSTRACT:
A system for guarding against the leakage of fluid from a hydraulic system, particularly an aircraft braking system, which employs a flow control valve under the control of an electronic processor. The electronic processor integrates with respect to time a function of the input signal to the flow control valve and the pressure of the output of fluid, compares the value of the integrated function with a predetermined value, and effects closure of the control valve if the comparison indicates a substantial fluid loss.
