Abstract
An electrically controlled, fluid driven actuator valve, in which an electrical signal drives a solenoid, which at any one time operates one of two flexible valve elements which, when opened causes a fluid pressure differential in a piston like hydraulic actuator chamber, to thereby drive an actuator rod, which then acts on any device desired to be controlled. The valve is of simple design with a minimum of moving parts, and is especially useful in missile and aircraft applications.
