INTEGRATED THREE FUNCTION VALVE

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 compone...

Summary: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 L'invention concerne une soupape intégrée à trois fonctions (ITFV), qui combine les fonctions d'une soupape de dérivation (p. ex. 183a, 185a, 161a) en un seul ensemble. L'ITFV assure un fonctionnement continu après deux défaillances quelconques. Avec la soupape intégrée à trois fonctions de l'invention, aucun cumul de défaillances d'un composant électrique ou hydraulique, quel que soit le taux de défaillances attendu, ne peut empêcher un actionneur de continuer de fonctionner de manière sûre.
