MAGNETOSTRICTIVE ELECTRONIC VALVE TIMING ACTUATOR

An apparatus and method for actuating a valve using magnetostrictive transduction is provided. A ferro-magnetic rod having giant magnetostrictive properties is operatively coupled with a hydraulic chamber. Application of a magnetic field to the ferro-magnetic rod generates strain in the rod and corresponding movement in a first piston, causing the fluid in the hydraulic chamber to become pressurized. The pressurized fluid forces a second piston to move, thereby actuating the valve.
