Abstract:
1. An electromechanical actuator for regulating a turbocharger of an internal combustion engine, comprising: a solenoid; a substantially solid ferromagnetic nucleus axially slidable within said solenoid, said ferromagnetic nucleus being balanced by a spring and having a rod at a first end thereof, the rod interacting with a pivot point of the turbocharger; a sensing system for sensing a position occupied by the ferromagnetic nucleus in the solenoid; and an electronic circuit which receives a first signal from the engine's electronic control unit and a feedback signal corresponding to a position of said ferromagnetic nucleus in said solenoid and that transmits to said solenoid a second signal for controlling a magnetic field produced by said solenoid.
