INTEGRATED THREE FUNCTION VALVE

Application 1661/KOLNP/2004 published 2006-08-04, filed 2004-11-04
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
