| Title of Invention | "INTEGRATED THREE FUNCTION HYDRAULIC VALVE ASSEMBLY FOR THE ACTUATION SYSTEM OF AN AIRCRAFT" |
|---|---|
| Abstract | An integrated three function valve (ITFV) that combines the functions of a bypass valve (e.g. 183a, 185a, 161a) into a single assembly is disclosed. The ITFV allows continued operation after any two failures. With the integrated three function valve, no combination of electrical or hydraulic component failures, regardless of expected failure rate, will prevent an actuator from continued safe operation. (FIG). 5 |
